The new v2.2.1 release has the correct fixes and the v2 tag has been updated

There was a small merge conflict between multiple PRs related to webpack and dist/index.js that our tests didn’t catch 😞 Sorry folks

Hello everyone! Yes, it looks like regression related to 2.2.0 release. Pull-request with fix https://github.com/actions/setup-python/pull/172 will be merged soon.

As a workaround, I suggest using new syntax for PyPy:

pypy-2.7
pypy-3.6
pypy-3.7
pypy-3.7-v7.3.3

See more examples in https://github.com/actions/setup-python#specifying-a-pypy-version

2.2.0 release was directed to add support for new PyPy syntax to allow installing PyPy on-flight and specifying exact version. But looks like we got regression in old syntax: https://github.com/actions/setup-python/pull/169
