2Hi @devendra, welcome to StackOverflow. It's worth reading the "How can I write a good question?" guide seen here (stackoverflow.com/help/how-to-ask). Your question here provides the error which is good, but there's a lot more information you could provide to make it easier to get to an answer. Checkout the guide for more info.Elliot Blackburn– Elliot Blackburn2018-10-31 16:08:02 +00:00Commented Oct 31, 2018 at 16:08

Since you're using Windows, you have to launch the terminal as administrator and retry should work.

It seems like this is a problem with npm. Try deleting your node_modules folder and running npm install again. This should fix the problem.

It may be possible that your package.json is open in some editor. Close it and then run the npm command again.

Try to uninstall the CLI using:
npm uninstall -g @angular/cli
and reinstall using:
npm install -g @angular/cli
and also try to update npm to latest version
npm cache clean --force
npm install -g npm@latest

It solved for me when I made this: Right-click on -What ever program I use- and select Run as Administrator. Personally I made it on PowerShell, but I assume that it works this way on any program

- Launch your code editor (eg.. Visual Studio Code) as Administrator.
- npm install -g @vue/cli.
- vue create yourprojectname.

Please try following steps:
- Delete node_modules
- Do npm cache clean --force
- Restart the PC
- Try again npm install, now modules will install without any issues
(optional) - If you are behind VPN and not using any private registry , exit VPN and do npm install after restarting pc

Okay, for me running as the administrator did not work at all. Nothing worked until I went into my root/global folder as shown below:
C:\Users\MyName
and in that folder I deleted the node_modules folder and any Angular config files that were globally put there. After doining that I went back to my local folder and it worked perfectly.
I hope this helps.

I had opened the project in multiple terminals. Later after closing all the respective terminals and running 'npm i', things started to work well.
