I am getting this error while installing material ui through npm. Please help me with the installation procedure of the same.

You can try using the command below:

npm install @material-ui/core --force

Or use legacy-peer-deps

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

One more issue may be your React version or node js version.If your node version is 12 try upgrading to version 16.You can do it using NVM.Using it you can manage multiple node versions in one machine.After installations use following command to use specific node version:

nvm use vA.B.C

One more solution is to clean cache using

npm cache clean --force 

Make sure you are installing in the folder that contains your package.json file

Add --legacy-peer-deps like this:
npm install @mui/material @emotion/react @emotion/styled --legacy-peer-deps
