Context
Vercel don't support yarn 2+ cache yet...
The workaround is to save the cache in node_modules, ie:
yarn install
becomesYARN_CACHE_FOLDER=./node_modules/.yarn-cache yarn install
.Bug
Setting YARN_CACHE_FOLDER will work, but not all the time, cause if a valid node_modules is not present initially it will fail
Reproduce
See #48
Try this to reproduce:
$ YARN_CACHE_FOLDER=./node_modules/.yarn-cache yarn install # -> BOOM will fail
PS: Weird, if your node_modules existed before it actually works:
$ yarn install $ YARN_CACHE_FOLDER=./node_modules/.yarn-cache yarn install # -> OK IT WORKS
But will fail if node_modules is not present (probably .yarn-state.yml)
