Reproduce Offline Mirror Errors for Scoped Packages on the Taobao Registry

You may have to manually remove the yarn local cache for @types/prop-types and prop-types to reproduce the error.

rm -rf ~/Library/Caches/Yarn/v4/npm-@types-prop-types-15.7.*
rm -rf ~/Library/Caches/Yarn/v4/npm-prop-types-15.7.*

After ensuring the cache does not exists, you can run

yarn --offline

to see the "cannot make request" error. Or run

yarn

to see the "integrity check failed" error (which happens randomly, depending on which package is to be fetched first I think).

Or you can execute reproduce.sh over and over again to see the caches and errors changing.
