Hi @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

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

Please try following steps:

  1. Delete node_modules
  2. Do npm cache clean --force
  3. Restart the PC
  4. 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

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

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