Definition for rule 'simple-import-sort/sort' was not found simple-import-sort/sort
It may be that you're using v6.
It looks like v6 doesn't have a
simple-import-sort/sort rule, see usage in the README. This was a change from v5 on Nov 15.
You probably need to make the following change:
- 'simple-import-sort/sort': 'error', + 'simple-import-sort/imports': 'error',
