use :

npm cache clean --force

See this https://github.com/npm/npm/issues/19072#issuecomment-345555468 I hope that solve your issue.

Answer 2

As I also went to the exact same problem using the NPM , which resulted in getting the same error as above . So instead of NPM i tried to use the yarn and it worked

Please try the following command

yarn add @material-ui/core

Answer 3

用 ' 包裹 @material-ui/core ：

    npm install '@material-ui/core'
