title: Attempted import error: 'alpha' is not exported from '@material-ui/core/styles'
body: <p>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 <code>npm install @material-ui/core@latest</code> and it worked fine. However, I lost the ability to use <code>createMuiTheme</code> &amp; <code>MuiThemeProvider</code>.</p>
