You probably have an invalid lockfile or npmrc.

[wiston-mwinzi]

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

[dmt0]

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.

Thanks! That seem to do the trick!

The issue occurs when the is some extra space in any particular line for yarn.lock file. A formatter for lock file will resolve this issue if you don't want to delete the lock file.

[sammerset]

The issue can occurs when the is some extra space in your .yarnrc file too

[veniti]

@ab-rnjn do you recommend any? prettier tells me that it can't format plaintext

[watermirror1107]

Remove the yarn.lock and install again, it can resolve your problem.
