Attempted import error: 'alpha' is not exported from '@material-ui/core/styles'

Question

I'm trying to use the material-ui/lab date picker, however I'm getting this error! I have updated my material-ui version using npm install @material-ui/core@latest and it worked fine. However, I lost the ability to use createMuiTheme & MuiThemeProvider.

Answer 1

Maybe it'll be helpful for someone. For me fix of that issue was to change the indirect import to direct one:

so this triggered the error:

import { Alert } from '@material-ui/lab'; 

this works fine:

import Alert from '@material-ui/lab/Alert'; 

Answer 2

You should update your package.json with following:

"@material-ui/lab": "4.0.0-alpha.57", "@material-ui/pickers": "3.2.10", 

Answer 3

I had the same problem with Skeleton using version @material-ui/lab": "4.0.0-alpha.60 but changing it to version @material-ui/lab": "4.0.0-alpha.57 fixed it for me ... guess they broke it again :)
