The command executed is NPM Install Web Pack-Dev-Server-Save-Dev. It will report an error without permission, and the command will still be reported if it is executed with administrator permission.
This error, however, can be successfully installed by changing it to NPM Install Web Pack-Server-Save. I don’t know why, but the great god will solve it.
PS: I also reported this error when I used Create-Reach-App to create the project directory before. I don’t know why I always reported this error when I used npm-related commands.
Run npm cache verify before reinstalling.
