TypeError: Cannot call a class as a function

[oste]

I am finding that deleting the yarn.lock file and attempting to reinstall can produce this error.

I am using yarn 1.22.15

.

You shouldn’t be deleting your lock file, why are you doing that?

[oste]

Yeah it’s probably not ideal to delete the lock file. Sometimes I do this to rule out other issues since it should provide e fresh install.

[nandorojo]

Yeah you shouldn’t remove it, that can mess up all the dependencies.

@oste @nandorojo This issue is caused in NextJS 12.0.3. Locking to 12.0.2 or 12.0.4-canary.4 will fix the issue

Issue causes by internal NextJS paths conflicting with the babel .web.ts path loading vercel/next.js#31116
