当我安装 material-UI 时，由 create-react-app 构建的 React（打字稿版本）应用程序中断

Question

I first used the command npx create-react-app my-app --template typescript to make a react application, which worked fine and there was no error in the console. then I executed npm install @material-ui/core to install material UI and after installing material-UI my react application starts showing the following error

Could not find a declaration file for module 'react'. 'C:/Users/91727/OneDrive/Desktop/test/node_modules/react/index.js' implicitly has an 'any' type.\n  If the 'react' package actually exposes this module, consider sending a pull request to amend 'https://github.com/DefinitelyTyped/DefinitelyTyped/tree/master/types/react`

Could not find a declaration file for module 'react/jsx-runtime'. 'C:/Users/91727/OneDrive/Desktop/test/node_modules/react/jsx-runtime.js' implicitly has an 'any' type.\n  If the 'react' package actually exposes this module, consider sending a pull request to amend 'https://github.com/DefinitelyTyped/DefinitelyTyped/tree/master/types/react`

Answer 1

As suggested in conversation about this issue , try to install @material-ui/core with --legacy-peer-deps option:

npm install --save --legacy-peer-deps @material-ui/core
