“Definition for rule '@typescript-eslint/consistent-type-assertions' was not found”

Hi,

There is a bug in the Create-react-app CLI.
Currently if you use and old package.json that has the : react-scripts: ^3.1.1 version.
and you run npm i and then try to rum the site (npm start) you get the following error:

“Definition for rule '@typescript-eslint/consistent-type-assertions' was not found”

I solved this by deleting the node_module entirely, then I updated my package.json file to use the "react-scripts: 3.1.2" version. then i run the npm i again, and it fixed the issue.

It looks like the new create-react-app doesn't backward support the react-scripts: 3.1.1 version.

Please check this ASAP since I already see posts in StackOverflow, meaning a lot of people are going to encounter this issue.

Thanks.

Thanks for the report. Likely because of our carat dependency on eslint-config-react-app. I imagine you're now seeing peer dependency warnings for @typescript-eslint/* packages as well?

/cc @iansu.

@iansu i forgot we had peer deps on @typescript-eslint packages, so should have likely been released as a breaking change for eslint-config-react-app. Probably worth re-evaluating including direct dependencies instead of peer deps for some in eslint-config-react-app?

Going to close as a dupe of #7709. Can continue discussion over there.
