You probably have an invalid lockfile or npmrc.

What does the invalid lockfile or npmrc mean and how can i resolve this?

[wiston-mwinzi]

This even happens when i do below

yarn init

I get

λ yarn init
yarn init v1.5.1

I'm experiencing the same issue! Is there a fix or workaround for this?

[navinesh]

I managed to get this working by deleting yarn.lock file and running yarn install

Why can't yarn tell me which line has this problem? I get the yarn-error.log, it has the whole package.json and the whole yarn.lock file in there, but nothing about the actual error that occured.
