material-ui@next doesn't support OutlinedButton?

<Button variant='outlined'>test</Button> Have no effect.And the Console output a warning! Like: Need I update local material-ui version? And how to update?

Initially, not yet. But as soon as you replace your imports, you might see some breaks in your code since some changes have definitely been made in the recent material-ui package releases.

e.g. Your typography import will now be: import Typography from '@material-ui/core/Typography';

Nothing much to worry about though, if there were any changes, they are definitely only minor ones. And on top of it, after successfully replacing your imports, you may now confidently use the current documentation without worries. 💯

As of https://material-ui-next.com/getting-started/installation/

Use @material-ui/core instead of material-ui@next
