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
I have NPM installed in my PC how to use it for a new project?
or do I have to install npm for every new project?
NPM is extremely useful, but, when you install it, you install it globally. It comes with Node JS, so when you install Node JS, you should have npm installed(type npm -v to see the version and whether npm is installed).
"npm init" creates a package.json for your folder, which contains all the information about the version number, the name of the project, and some other information. In package.json, you can add dependencies, which basically say your project relies on that npm package.
"npm install" will install all the packages specified in package.json, and, if you want to install something specific, you would type "npm install ".
I'd like to know if Javascript's npm installs dependencies OS-wide like Python's pip (if pip is not using a virtualenv), or if npm installs dependencies more like Java's mvn which stores the things in a local pom.xml file (to me mvn feels more like if it was always in a virtualenv if compared to pip).
So I mainly want to know if it's OS-wide installs or local installs that are performed with npm.
Both!!
npm install -g PACKAGE_NAME will install the package globally.
npm install PACKAGE_NAME will install the package locally in the current folder, under node_modules/.
npm install --save PACKAGE_NAME will install the package locally and save it as a dependency in your package.json.
Checkout https://www.sitepoint.com/beginners-guide-node-package-manager/
if you execute just npm install <dependency name> you are telling node to install package only on your current directory this will also create node_modules in current directory you are installing.
and if you execute the npm install -g <dependency name> with the -g you are saying that you want the node to install the dependency globally and the package will be save on the global node_modules. and most of the global dependencies can be access using CLI
example.
$ npm install mocha
you can execute the command in the current directory execute the npm install or where the node_module is
$ $PWD/node_modules/.bin/mocha -v
if you
$ npm install -g mocha
you can execute the command anywhere in your directory on the terminal
$ mocha -v
I have a workspace on c9.io, and I am using node.js. I am trying to update socket.io from 0.9.17 to the latest version. However, whenever I run the command npm update socket.io it installs the same version. How can I fix this?
To install the latest available package:
npm install <package>
To install a version directly (no need to uninstall first):
npm install <package>#<version>
If you're not sure what versions of a package are available, you can use:
npm view <package> versions
Don't forget the --save flag to add dependencies to your package.json file.

About npm update
However, if app's package.json contains:
"dependencies": {
"dep1": "~1.1.1"
}
In this case, running npm update will install dep1#1.1.2. Even though the latest tag points to 1.2.2, this version does not satisfy ~1.1.1, which is equivalent to >=1.1.1 <1.2.0. So the highest-sorting version that satisfies ~1.1.1 is used, which is 1.1.2.

What happens when you do npm install in a dev environment on a project that has both a package.json and a npm-shrinkwrap.json file?
Will it ignore the shrinkwrap and use package.json for everything or just for the dev dependencies?
Any files added to the production dependencies in package.json will be ignored if they are not in the npm-shrinkwrap.json. Vis-à-vis: running npm install with foo-package added to the production dependency list will not install foo-package.
Not so for devDependancies.
Running npm install with foo-package added to the devDependency list will install foo-package even if it is not found in the npm-shrinkwrap.json file.
Fun.
