Answer 1

由于您使用的是Windows ，您必须以as administrator身份启动终端as administrator然后重试即可。

Answer 2

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.

Answer 3

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

Answer 4

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

Answer 5

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

Answer 6

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

Answer 7

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

Answer 8

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