Eslint uninstall - javascript

I uninstall eslint from my system by running two commands i.e
npm uninstall eslint --save-dev (to remove it from the package .json)
npm uninstall eslint
But after doing all this when I run this command npm eslint -v, it shows me the version of the eslint.
How do I completely remove eslint from my system?

Try to check globally installed packages using the below command:
npm list -g
And if you find eslint in the list then try to use this command:
npm uninstall -g eslint --save

Cannot install Vue Cli on Mac Catalina [duplicate]

While installing the dependencies of vue-cli, vue is not identified. Why?
rm -rf node_modules and npm install again
have a look here
Add sudo before yarn when installing
yarn global remove #vue/cli
sudo yarn global add #vue/cli
vue
I had the same issue for a while.
TL;DR
npm install #vue/cli-service --save-dev
As the documentation specify it is a development dependency https://cli.vuejs.org/guide/#cli-service
The CLI Service (#vue/cli-service) is a development dependency. It's an npm package installed locally into every project created by #vue/cli.
Origin
I had a fresh install of nodejs
And just did
>> sudo npm install -g #vue/cli#latest
>> vue --version
#vue/cli 4.5.8
The issue
The issue presented like this
>> npm run serve
yarn run v1.22.10
$ vue-cli-service build --mode development --watch
/bin/sh: 1: vue-cli-service: not found
error Command failed with exit code 127.
info Visit https://yarnpkg.com/en/docs/cli/run for documentation about this command.
The fixes:
npm install #vue/cli-service --save-dev
Which led me straight to another error message
>> npm run serve
yarn run v1.22.10
$ vue-cli-service build --mode development --watch
ERROR Error: Cannot find module 'vue-template-compiler/package.json'
Which I fixed the same way
npm i vue-template-compiler --save-dev
And now it is working fine.
Installing current version without permanently installing vue-cli.
npx #vue/cli create appname
It shows the vue executable is located at /home/alisha/.local/bin. So probably this location is not there in your $PATH.
You should be able to run the vue commands if you provide the full path, like:
~/.local/bin/vue create hello-world
You can also see if that directory is in your PATH by running some command like:
echo $PATH | grep '.local/bin/'
If it's there, you would see it, otherwise you can add it to your path by placing it in your ~/.profile.
Edit ~/.profile and add the following at the bottom of it.
PATH="$HOME/.local/bin:$PATH"
Hope it helps!!
I had the same issue while making a build for production.
You will require vue-cli to be installed. Use below command to install the latest version.
npm install -g #vue/cli#latest
Then
npm install
Might have to do with you having an old version on your computer:
Warning regarding Previous Versions
The package name changed from vue-cli to #vue/cli. If you have the previous vue-cli (1.x or 2.x) package installed globally, you need to uninstall it first with
npm uninstall vue-cli -g or yarn global remove vue-cli.
You can find it here: https://cli.vuejs.org/guide/installation.html
THIS FIXED THE ISSUE FOR ME:
After running
sudo npm install -g #vue/cli
I ran
sudo nano $HOME/.profile
and pasted the following line
export PATH=$PATH:/home/chike/.npm-global/bin
after writing the code, next thing I did was Ctrl + O, ENTER and Ctrl + X then wrote
vue init webpack myapp
When you install vue using cli that time you got the path of vue.Now you can copy the bin folder path.
In my example /home/sublime/.npm-packages/bin
Now you export the path below command
export PATH=$PATH:/home/sublime/.npm-packages/bin
I solved mine by running (add sudo if needed)
npm i -g vue-cli#2.9.6
npm i -g #vue/cli
Got similar issue when deploy vue project in jenkins.
Here is what I did:
Add node's bin/ dir, to jenkins user's .bashrc file.
e.g
# node
NODE_HOME=/home/dev/.nvm/versions/node/default
PATH=$NODE_HOME/bin:$PATH
Tips - about nvm & yarn
When you manage node version via nvm, make sure you already choose the node version in terminal. e.g:
nvm use stable
node -v
If you use nvm, and installed yarn via npm, then better install vue-cli via npm not yarn, otherwise the vue executable is not placed into node's bin/ dir, at least that's the case in my tests, and as a result will cause you fail to find the vue command.
Using Yarn on Ubuntu it is installed to ~/.npm-packages/bin/. You must add this directory to your PATH. For example run the following command, close your terminal and open a new one.
user#machine:~$ echo 'export PATH="$PATH:~/.npm-packages/bin/"' >> ~/.bashrc
Note: if the file ~/.bashrc does not exist then simply create it.
Following worked for me:
First remove all the existing ones:
yarn global remove #vue/cli
yarn global remove #vue/cli-service
sudo yarn global remove #vue/cli
sudo yarn global remove #vue/cli-service
Then add #vue/cli using sudo:
Note: use sudo if required
yarn global add #vue/cli
yarn global add #vue/cli-service
Then, the final thing to do is to RESTART the terminal.
vue --version
#vue/cli 4.5.9
If you already got a project, the only two things you need to do is:
Delete the directory node_modules (it is safe, since it is not under git and will regenerate in the next step)
In the command-line write yarn install (it will install everything you need)
If you start installing vue-cli manually in a existing project, it the package.json and package-lock.json will be updated. If you already did. Do a checkout from git, and follow my steps above
This may be a problem caused by version conflicts. "export PATH=$PATH:" This is really useful in some cases. But if you are also like me, after trying the direct “export path” method in the comment above, restarting the terminal still can not execute the situation, you can try this way.
Uninstall Vue
npm uninstall -g #vue/cli
Check the local-global npm package installation path, vue is installed in this directory, check if it has been removed.
npm root -g
Install vue (you can check with https://cli.vuejs.org/#getting-started to find the latest command)
npm install -g #vue/cli
Create a connection to the /usr/local/bin directory(You need to find the vue.js path after the local installation first, then replace this path with your latest local install path:/Users/xxxxx/.npm-global/lib/node_modules/#vue/cli/bin/vue.js)
ln -s /Users/xxxxx/.npm-global/lib/node_modules/#vue/cli/bin/vue.js /usr/local/bin/vue
View version number
vue -v
I was getting the same error because Node.js was not installed. My issue got resolved by installing Node.js using the following command:
sudo apt install nodejs-legacy
To see if you already have Node.js and npm installed and check the installed version, run the following commands:
node -v
npm -v
If both are installed then follow the steps here:
https://docs.npmjs.com/resolving-eacces-permissions-errors-when-installing-packages-globally
I installed the package using yarn global add #vue/cli on my Ubuntu box and found the binary in /home/vonkad/.yarn/bin.
I had to modify my /home/vonkad/.bashrc and add the directory to the path export PATH=$PATH:/home/vonkad/.yarn/bin.
To fix this situation, I had to add the following line to my .zshrc (maybe in your case is .bashrc)
export PATH="$(yarn global bin):$PATH"
Effectively, the yarn global bin is a folder where vue (vue-cli 3) was placed.
What helped me
mac os catalina with zsh terminal
Uninstalled node and npm using https://www.positronx.io/how-to-uninstall-node-js-and-npm-from-macos/
Downloaded node/npm from https://nodejs.org/en/download/current/
sudo npm install -g #vue/cli
vue --version (#vue/cli 4.5.4)
I faced the same issue and now resolved. In my case I installed Node.js and NPM using the default Ubuntu repository by using this command sudo apt-get install nodejs npm
The problems seemed like those 2 packages are not well maintained so it caused some bugs.
So I purge those packages and reinstall it from nodesource which is officially recommended way to install (reference: Installation instruction from nodesource) using these commands.
curl -sL https://deb.nodesource.com/setup_14.x | sudo -E bash -
sudo apt-get install -y nodejs
Then reinstall #vue/cli again
sudo npm install -g #vue/cli
Now these issues have gone. Hope it helps some programmers.
You need to install vue via sudo like explained in the doc:
https://cli.vuejs.org/guide/installation.html
If you have WSL2 running and you use zsh like me, just add
yarn global add #vue/cli
# add this line to ~/.zshrc
export PATH="$HOME/.yarn/bin:$PATH"
$ vue --version
#vue/cli 4.x.xx
You can try the following code install see
npm install --global vue-cli
vue init webpack <YOUR-PROJECT-NAME-HERE>
cd <YOUR-PROJECT-NAME-HERE>
npm install
npm run dev

npm error code EINVALIDTAGNAME when trying to install protobufjs

I got an error when installing protobufjs with this command:
npm install protobufjs [--save --save-prefix=~]
the error is:
npm ERR! code EINVALIDTAGNAME
npm ERR! Invalid tag name "[--save": Tags may not have any characters that encodeURIComponent encodes.
How can I fix this issue?
Where did you find that syntax?
Square brackets in the instructions for how to run something generally mean that the part in square brackets is optional. i.e. that you can run the command with or without the part in square brackets.
For npm you can run:
npm install protobufjs
or
npm install protobufjs --save-prod
or
npm install protobufjs --save-dev
etc., depending on what you're trying to do.
I believe older versions of npm used --save instead of --save-prod and in later versions of npm, --save-prod is the default.
$ npm --version
6.4.1
$ npm install protobufjs
npm notice created a lockfile as package-lock.json. You should commit this file.
+ protobufjs#6.8.8
added 14 packages from 35 contributors and audited 16 packages in 4.502s
found 0 vulnerabilities
Just simply use the following Syntax #nodejs #Express
npm install protobufjs
Insted of :
npm install protobufjs --save-prod
or
npm install protobufjs --save
Because the newer version of Nodejs by default having --save method
As best answer says:
prefix=~]
that's the problm
in my case was just a + for this line:
npm install --save request request-promise cheerio puppeteer+
copy-pasting from website, make me do this mistake
hope it works

How to install gulp jshint using npm?

Unable to install JSHint. Can anyone suggest me what I am doing wrong?
I am using below command.
npm install --save-dev gulp-jshint gulp-jscs jshint-stylish
It is showing the following "gulp-jshint#2.0.4 requires a peer of jshint#2.x but none was installed-UNMET peer dependency"
Try executing the following command npm install --save-dev jshint gulp-jshint gulp-jscs jshint-stylish
peer dependency is not installed by npm you must install it manually before.
In your case :
npm install --save-dev jshint
Update
Peer dependency is a dependency for a library that is not required. It is considered as a plugin.
You can find more informations here for npm or here for nodejs

Installing Angular-CLI on Windows 10

I had installation issues of angular-cli on Windows 10 system.
The errors were related to Python dependencies and node-gyp. Something as below :
>execSync#1.0.2 install C:\Users\UserName\AppData\Roaming\npm\node_modules\angular-cli\node_modules\execSync
node install.js
[execsync v1.0.2] Attempting to compile native extensions.
{ Error: spawn node-gyp ENOENT
at exports._errnoException (util.js:1007:11)
Update
this seems to be fixed in newer releases and this solution is no longer required.
mukesh51 eventually solved the problem.
the installation seems to work in these steps:
npm install -g node-gyp
npm install -g windows-build-tools
npm install -g #angular/cli
I took these steps from here.
Uninstall
npm uninstall -g angular-cli
npm uninstall --save-dev angular-cli
Update Global package
npm uninstall -g #angular/cli
npm cache clean
npm install -g #angular/cli#latest
I too faced the same issue initially when I installed angular directly using bash. The installation was error completely. Then I attempted to install locally in my project (without removing the global one). That appeared to have solved the problem but got an error on creating a new app.
So i uninstalled everything :
npm uninstall -g #angular/cli
and the reinstalled Angular using Windows Power Shell(as Admin)
npm install -g #angular/cli
This solved the entire problem! Hope it helps!
Use windows power shell to install angular-cli. It will run without any issues.
Windows 10 Solution
Look back at the trace of installation steps ... you may see that it found the Angular binary in the following location:
C:\Program Files\Git\usr\local\node_modules\#angular\cli\bin
I added an ENVT variable using this path and ng worked fine after that
I tried using npm install -g #angular/cli
npm downloaded files successfully and copied files to AppData but not able to use ng -v
After that, I tried following:
npm cache clean --force
Removes npm cache forcefully if you get warning using npm cache clean.
Then try
npm install -g #angular/cli#latest
I have successfully installed by trying the above solution in Windows10.
Both the CLI and generated project have dependencies that require Node 8.9 or higher, together with NPM 5.5.1 or higher.
try update node.js and npm
npm uninstall -g #angular/cli
npm install -g #angular/cli
if doesn't work:
Close the terminal, open a new one or use CMD or Git for windows instead.

After installation of Gulp: “no command 'gulp' found”

After installing gulp.js via npm, I receive a no command 'gulp' found error when running the gulp command from the same directory it was installed into.
When looking under the node_modules/.bin/ directory, I can see the gulp executable there.
Is there something wrong with my npm installation?
That's perfectly normal.
If you want gulp-cli available on the command line, you need to install it globally.
npm install --global gulp-cli
See the install instruction.
Also, node_modules/.bin/ isn't in your $PATH. But it is automatically added by npm when running npm scripts (see this blog post for reference).
So you could add scripts to your package.json file:
{
"name": "your-app",
"version": "0.0.1",
"scripts": {
"gulp": "gulp",
"minify": "gulp minify"
}
}
You could then run npm run gulp or npm run minify to launch gulp tasks.
I solved the issue without reinstalling node using the commands below:
$ npm uninstall --global gulp gulp-cli
$ rm /usr/local/share/man/man1/gulp.1
$ npm install --global gulp-cli
I actually have the same issue.
This link is probably my best guess:
nodejs vs node on ubuntu 12.04
I did that to resolve my problem:
sudo apt-get --purge remove node
sudo apt-get --purge remove nodejs
sudo apt-get install nodejs
sudo ln -s /usr/bin/nodejs /usr/bin/node
I solved the issue removing gulp and installing gulp-cli again:
rm /usr/local/bin/gulp
npm install -g gulp-cli
if still not resolved try adding this to your package.js scripts
"scripts": { "gulp": "gulp" },
and run npm run gulp
it will runt gulp scripts from gulpfile.js
Installing on a Mac - Sierra - After numerous failed attempts to install and run gulp globally via the command line using several different instructions I found I added this to my path and it worked:
export PATH=/usr/local/Cellar/node/7.6.0/libexec/npm/bin/:$PATH
I got that path from the text output when installing gulp.
Tried with sudo and it worked !!
sudo npm install --global gulp-cli
I'm on lubuntu 19.10
I've used combination of previous answers, and didn't tweak the $PATH.
npm uninstall --global gulp gulp-cli
This removes any package if they are already there.
sudo npm install --global gulp-cli Reinstall it as root user.
If you want to do copy and paste
npm uninstall --global gulp gulp-cli && sudo npm install --global gulp-cli
should work
I guess --global is unnecessary here as it's installed using sudo, but I've used it just in case.
in my case there was only on issue, just put "gulp":"gulp" in the script portion, of package.json, and then use command npm run gulp.
