ERR! code ELIFECYCLE - Error while executing TodoMVC - javascript

I am trying to use TodoMVC for comparing performance of some JS frameworks.
I have done a clone of online repository,$ npm install inside main directory, the command $ gulp test-server is executed correctly (application started on http://localhost:8000/) but when i run $ npm run test it shows the following errors which i don't know how to solve
enter image description here -> this is solved
enter image description here -> For the second error i have tried to do
1)npm cache clean --force
2)delete node_modules folder
3)delete package-lock.json
4)npm install
but is still shows the same error and can not run $ npm run test
Cypress installation error -> enter image description here

The port 8000 is already in use, this is written black on white in the image you linked, first line of the error message, so you already have a server using that port. that's what EADDRINUSE means. Kill the process listening at 8000 or launch your tests on another address if possible.

For your second error try to install Cypress globally:
sudo npm install -g cypress
And than try to run the test

bin is not recognized as an internal or external command. npm script

I'm new to node/npm and having an issue trying to start an npm script.
When I try to run a basic script like the one belown, it gives me the error "bin is not recognized as an internal or external command". I think i have had already run succesfully some previous script I made so I don't know if wether my npm is broken or if I did something wrong.
#! node
const app = require('../lib/app')
const config = {
port: 8080
}
app.listen(config.port, () => {
console.log(`Chat is waiting for you at http://localhost:${config.port}`)
})
Screenshot bin error
I have already tried uninstal - reinstall it.
I also checked this post: npm bin command - not recognized as an internal or external command and tried to run npm install -g unsucessfully.
I'm on Windows.
Nevermind.
I just understand what happend. The code was inspired from a Linux user which had the "! env node" on the first line.
I'm on Windows so I removed it but as a result, the script was just trying to run "bin/start" instead of "node bin/start".
Ridiculous error but well, at least i've learned something

Jenkins-Protractor Integration-Centos7

I am facing problem while integrating Jenkins with protractor script.
Steps:-
1. Created Freestyle project and i selected 'Execute Shell' build option and put protractor --version command.
When i build this simple job it says:- + protractor --version
/tmp/jenkins5545881549145932714.sh: line 2: protractor: command not found
Same applies to npm --version, when i run this command got error :- npm: command not found.
But node --version works fine.
I am using centos7, and when i ran these commands on server command line, it works like charm.
Please Help!!
When I had similar problem, devops fixed it by adding a statement to the command so in the result I had
export PATH=/home/ubuntu/bin:/home/ubuntu/.local/bin:/home/ubuntu/.nvm/versions/node/v10.15.3/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin; cd ui-automation; protractor conf.js
still not completely understand what that does...
If that doesn't help, make sure your protractor and everything else are globally installed
You can get the global package install path via npm config get prefix
NPM_PREFIX=`npm config get prefix`
export PATH=$NPM_PREFIX/bin:$PATH
protractor --version

NPM Install giving rollbackFailedOptional

After trying to use the Windows Powershell (as an admin), the command prompt (as an admin) and the bash CMD; I repeatedly get the following error after trying an npm install command:
npm install npm#latest -g
is the attempted command and...
[...] / rollbackFailedOptional: verb npm-session xxxxxxxxxxx
where the 'x's represent different letter and number combinations at each attempt, is the message. I am aware that this should be the first step in the installation of a package but it remains on this message for a long time and will not change.
I am trying to use the JavaScript React library, more specifically the 'create-react-app'. The npm install -g create-react-app command is also causing the error.
npm version: 6.5.0
npx version: 10.2.0
node version: 10.15.0
A solution would be greatly appreciated.
https://docs.npmjs.com/try-the-latest-stable-version-of-npm In this link there is the documentation for updating npm version for windows with a link to a tool developed by Microsoft to update npm (https://github.com/felixrieseberg/npm-windows-upgrade)
I found the solution:
As my device username has both my first and last names, with a space in between, npm was reaching errors because of this. So the solution was to uninstall node from the default location and reinstall it in a folder on my C:\ drive, where there were no files in the directory that have spaces in the names. I then changed the cache location into this same C:\ drive folder, and the problem was solved.
npm config set cache C:\NODEJS\npm-cache
(these folders must be created before you can set the config directory to these.)
For me, I ended up having to:
Uninstall Node.js
Remove the folder "nodejs" completely from C:\Program Files (or
wherever you decided to install node)
Reinstall Node.js
After that, I did not encounter [...] / rollbackFailedOptional: verb npm-session xxxxxxxxxxx anymore.
I'm not quite sure what the issue was but all suggestions I found on stack did not solve this problem for me. I hope this helps someone.
Check if you are connected to any other VPN or proxy setting. If so try to disable it or disconnect from it and then execute the npm command. It worked for me. In my case, I was using the organization laptop and was connected to external vpn network, so i disabled the vpn and tried the command and it worked.
In our case the hard disc of the nexus server (repository server) was just full. Maybe someone helps this. Before looking into other more complicated options.
for my case i uninstalled the reinstelled it and used powershell insted of cmd and it worked like a charm
First run these commands.
npm config rm proxy
npm config rm https-proxy
then run this.
npm config set registry https://registry.npmjs.org/
check if the internet is connected
and try to run the npm command which was giving the error.

npm - EPERM: operation not permitted on Windows

I ran
npm config set prefix /usr/local
After running that command,
When trying to run any npm commands on Windows OS I keep getting the below.
Error: EPERM: operation not permitted, mkdir 'C:\Program Files (x86)\Git\local'
at Error (native)
Have deleted all files from
C:\Users\<your username>\.config\configstore\
It did not work.
Any suggestion ?
Running this command was my mistake.
npm config set prefix /usr/local
Path /usr/local is not for windows. This command changed the prefix variable at 'C:\Program Files (x86)\Git\local'
To access and make a change to this directory I need to run my cmd as administrator.
So I did:
Run cmd as administrator
Run npm config edit (You will get notepad editor)
Change prefix variable to C:\Users\<User Name>\AppData\Roaming\npm
Then npm start works in a normal console.
This is occurring because windows is not giving permission to the user to create a folder inside system drive. To solve this:
Right Click
The Folder > Properties > Security Tab
Click on Edit to change Permissions > Select the user and give Full Control to that user.
Sometimes, all that's required is to stop the dev server before installing/updating packages.
I solved the problem by changing windows user access for the project folder:
Here is a screenshot:
http://prntscr.com/djdn0g
Restarting VsCode solved it for me!
I recently had the same problem when I upgraded to the new version, the only solution was to do the downgraded
To uninstall:
npm uninstall npm -g
Install the previous version:
npm install npm#5.3 -g
Try update the version in another moment.
I use Windows 10.
I started the CMD as administrator, and it solved the problem.
Find CMD, right click, and click open as administrator.
I had an outdated version of npm. I ran a series of commands to resolve this issue:
npm cache clean --force
Then:
npm install -g npm#latest --force
Then (once again):
npm cache clean --force
And finally was able to run this (installing Angular project) without the errors I was seeing regarding EPERM:
ng new myProject
In my case, I was facing this error because my directory and its file were opened in my editor (VS code) while I was running npm install. I solved the issue by closing my editor and running npm install through the command line.
I had the same problem, after updating npm. Solved it by re-installing latest npm again with:
npm i -g npm
but this time with cmd running in administrating mode.
i did all this because i suspected there was an issue with the update, mostly some missing files.
I had the same problem when I tried to install the npm package AVA. The solution for me was to delete the node_modules folder and force-clean the npm cache:
rm -rf node_modules
npm cache clean --force
I could then install the npm package without a problem.
for me it was an issue of altering existing folders in node_module, so i nuked the whole folder and run npm install again. it works with no errors after that
Just run cmd as admin. delete old node_modules folder and run npm install again.
The Problem I faced (In Windows Computer)
When I was trying to install a couple of npm packages I got the following error:
npm - EPERM: operation not permitted - while npm was trying to rename a file
Here's my debug snippet for reference, if you've faced the similar problem:
After carefully checking out the answers from other users, I have created a detailed answer for the community
My Solution for the problem
Follow the mentioned steps
Right-click on the project folder
Go to properties -> Security Tab
Select Users -> Edit
In the Permission for Users section, Full control -> Give a check mark in Allow -> OK
Wait for Windows security to apply the new security rules
Click OK
Visualization of the steps
If you follow these steps and try to install npm packages again it will work properly.
Note: It's a best practice to close and open up the command line again to experience the changes
Simplest way
Hope I am not too late for this post but recently even I too got hit by this issue. And also I had no admin rights on my laptop.
Here is the simplest way I fixed the bug.
Locate the file name .npmrc (it will be in C:\Users\<user name>\.npmrc)
Open it and change the path of prefix= to prefix=C:\Users\<user name>\AppData\Roaming\npm
hope it will be helpful..
Happened to me since the folder/file was locked by another process. Used a tool (LockHunter) to terminate that process and it started working again (possible reason).
If you getting this error in an IDE's terminal/commands prompt, try delete node_modules, close IDE, and run the npm install command again.
The time when IDE started but still not completed its analysis of node_modules tree is a tricky moment, when packages installation may fail because IDE still scanning node_modules contents.
This error is caused by different problems try the below one of them will work for you!
try to run npm as Administrator
Run cmd as administrator npm config edit (You will get notepad editor)
Change Prefix variable to C:\Users\<User Name>\AppData\Roaming\npm
The errors went after I disabled my anti-virus (Avast)
Sometimes a simple cache clear like the below would fix it.
npm cache clear
For me the problem come from bash terminal. I change my terminal to powershell and it's ok.
Really easy to resolve
Find this command npm cache clean as a solution to those error in quick and simple way!
I updated my node version to 8.9.4 and ran the necessary install command again from administrator command prompt. It worked for me!
A reboot of my laptop and then
npm install
worked for me!
Running npm commands in Windows Powershell solved my issue.
Try npm i -g npm . NPM version 6.9 is work to me.
Apparently anti-virus software can also cause this error. In my case I had Windows Security's Ransomware Protection protecting my user folders which caused this error.
Windows 10,
Running the IDE (in my case IntelliJ) in administrator mode and executing npm install does resolves the problem.
If no IDE then run CMD in administrator mode and try executing npm install
For those trying to update config
If having trouble updating your npm config, try instead running using the -g flag. This solved the issue on Win 10 for me after trying everything else.
npm config edit -g
I am able to update the config and changes are reflected everywhere. This may be due to running npm in an organizational scope.
I was running create-react-app server. Simply stopped the server and everything worked just fine.
The simpler way to solve this by entering the below command
npm config set cache C:\tmp\nodejs\npm-cache --global
At least I just solved my problem in this way:
Search cmd
Then run as administrator
Then npm i -g expo-cli or npm config set prefix /usr/local
I just solved my problem.

Grunt.js Installation Issue - Command Not Found

I'm trying to get grunt.js set up on my work machine. Now I've managed to get it set up at home, so I pushed my repository, then cloned it on my work machine, however despite troubleshooting this to death I've always run into the same issue when I come to try and run the command on my work computer;
sh.exe": grunt: command not found
So some background and explanation;
I'm using Aptana 3.0 and running all my commands through the terminal. (This applies to my home and work computer)
I cloned the "working" repository and put it in a folder on my work machine, so I have my package.json and gruntfile.js files inside said directory. These work fine on my home computer and I am able to run the watch task set up in my gruntfile.js successfully at home.
I've run npm install grunt-cli -g and npm install inside my project on my WORK computer and installation has been successful each time. My only error messages on either are a lack of description and a repository field which, to my knowledge these aren't mandatory?
The node modules folder inside my repository indicates I have the following installed (as per my package.json)
grunt
grunt-contrib-compass
grunt-contrib-uglify
grunt-contrib-watch
matchdep
Now I'm pretty green to this command line stuff, so I may have overlooked something very obvious but I feel like I've tried every guide going to get this thing to work.
Despite running through the getting started steps/installing grunt documentation repeatedly, it seems no matter what I do the terminal will not pick up grunt as a recognized command.
Am I stupid or is this some other issue?
EDIT 1: contents of my package.json:
{
"name" : "xxxxxxxxx",
"version" : "xxxx",
"dependencies" : {
"grunt":"~0.4.1",
"grunt-contrib-watch": "~0.5.3",
"grunt-contrib-compass": "~0.5.0",
"grunt-contrib-uglify": "~0.2.2",
"matchdep": "~0.1.2"
}
}
This is happening because you are using the Aptana Terminal, which needs the PATH variable to work out what is meant by grunt etc. A normal cmd prompt would work fine with the command npm install grunt-cli -g but in this context the terminal is unaware of what grunt is.
As per the following existing answer, you need to set up your Windows PATH variable to make the Aptana Terminal aware of the npm directory: https://stackoverflow.com/a/19137584/463205
C:\Users\Username\AppData\Roaming\npm
Closing the terminal and reopening it after setting the PATH correctly should enable you to run the command successfully.
Try to run
npm install grunt-cli -g
On your home computer.
-g means - install Grunt globally (not in the project node_modules folder), so it'll add grunt command to the bin folder which is used by nodejs console ( and you need to run node.js command prompt, not just arbitrary cmd)
