Mac Os error: Error: Cannot find module '/Users/xxx/.yarn/releases/yarn-1.22.1.js'

[bgits]

Running MacOs Catalina 10.15.7.

After receiving warnings about yarn being out of date I tried to upgrade it. I have tried several means and yarn no longer works on the machine.

After initially using yarn upgrade

I tried using the curl script: curl -o- -L https://yarnpkg.com/install.sh | bash -s -- --rc

The install terminates with:

internal/modules/cjs/loader.js:834
  throw err;
  ^

Error: Cannot find module '/Users/xxx/.yarn/releases/yarn-1.22.1.js'

  requireStack: []
}
> Yarn was installed, but doesn't seem to be working :(.

which yarn returns /Users/xxx/.yarn/bin/yarn

Wondering how to get past this and yarn working again?

I have the exact same problem. Frustrating to see that due to no solution I will have to - what exactly? Buy a new pc?

I found a .yarnrc file (can't remember the exact name). Deleted it. And now everything works!!!!!

Got the idea because yarn worked in other folders. So If you encounter this: look for a .yarn file in the folder, remove it and hope for the best.

Yep, Yarn will look for .yarnrc and .yarnrc.yml files and read the yarnPath field to spawn the specified binary. If the binary doesn't exist, it crashes. These files with a yarnPath are created when running yarn set version / yarn policies set-version, which are for per-project installs, so don't run it in your home directory. If you accidentaly do, just delete the generated .yarnrc / .yarnrc.yml file.

Much appreciated @paul-soporan !

Reason

I once upgraded Yarn using yarn set version latest and did not realize that it produces .yarnrc in my home directory.

Solution

1. Removing .yarnrc (it existed in home directory in mycase. Make sure you are in the directory where .yarnrc remains) :

rm .yarnrc

2. I loaded profile config (e.g. : .bashrc, .zshrc, etc.) with :

source ~/.zshrc

---

Finally yarn -v worked again.

@paul-soporan

so don't run it in your home directory.

You have made my day with this solve 😄 was going nuts trying to understand why .yarn/releases/yarn-1.22.1.cjs --version was giving me 3.1.0. Sure enough, I had yarn configs in my home dir.

If

rm .yarnrc

does not work. make sure to also do

rm .yarnrc.yml
