I'm getting an error that might be related to this merge. Is the change expected?

AttributeError: module 'virtualenv.activation.python' has no attribute 'PestythonActivator'

[sstoops]

This just broke all of my production build pipelines as well.

[gaborbernat]

I have to be honest, have no idea how this change made it in. Late Friday releases are always dangerous but wanted to get out a fix release to address peoples issues due to #1846 🤦 🤷‍♂️

[victor-torres]

It happens. Thanks for the quick fix! @gaborbernat

[victor-torres]

Same issue here:

AttributeError: module 'virtualenv.activation.python' has no attribute 'PestythonActivator'

It's affecting my Bitbucket Pipelines :/

[phrfpeixoto]

Haha. It seems we're missing tests here.
