Full output:

I tried removed node_modules, re-ran yarn install and yarn add --dev jest to no avail.
How do I fix this?
Answer
yarn cache clean
To fix this, run:
yarn cache clean
yarn add --dev jest
From the yarn cache documentation:
yarn cache clean [<module_name...>]Running this command will clear the global cache. It will be populated again the next time yarn or yarn install is run. Additionally, you can specify one or more packages that you want to clean.
You can also see where the cache is with yarn cache dir.
yarn cache dirRunning yarn cache dir will print out the path where yarn’s global cache is currently stored.
