As noted above yarn cache clean should deal with most issues. However, today I came across this situation and none of these worked for me:

yarn cache clean
yarn cache clean --force
yarn cache clean --mirror
yarn cache clean --all

The issue was that by running npx, or perhaps an npm/yarn command earlier there was a package.json file that was created in my home directory with nothing in it

by removing this file via

rm ~/package.json

yarn (and npx commands that invoke yarn) were able to run successfully in my project
