Cannot use MUI 'ContentCopy' icon

Question

I am trying to use the icon 'ContentCopy' from MUI.

import ContentCopyIcon from '@mui/icons-material/ContentCopy';

No matter what I do, I get the error:

Module not found: Can't resolve '@mui/icons-material/

I have already tried the following:

npm install @material-ui/core
npm install @material-ui/icons

I also tried deleting my node-modules and re-running npm install.

Any ideas on what else I could try??

It seems that you confused of using version 4 and 5.

You need to install the icons of version 5.

npm install @mui/icons-material

And import the icon from the module.

import ContentCopyIcon from '@mui/icons-material/ContentCopy';

to version 5 you need to install mui

npm install @mui/icons-material

mui contains all the icons

from '@mui/icons-material/_';
