So I'm getting this error when I try to do a yarn install. I can yarn start without issue but i'm not sure if it's causing an issue behind the scenes so i'd like to resolve it.

TypeError: Cannot create property 'lastUpdateCheck' on string 'lastUpdateCheck 1599160669280'

at Install.<anonymous> (/usr/local/Cellar/yarn/1.22.5/libexec/lib/cli.js:7930:35)
at Generator.next (<anonymous>)

i've tried deleting my yarn.lock and basically every file i could find that had yarn in it and reinstalling. I've tried installing yarn through yvm instead of brew. None of these things have had any affect.

Any help is greatly appreciated.

Have you tried removing the ~/.yarnrc file? I had a corrupted .yarnrc file that was preventing me from installing.

Running this should remove your yarnrc.

rm ~/.yarnrc

Experienced this issue with WSL but it should be applicable in other cases.

I also submitted and later resolved an issue 8469
