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

Definitely something wrong, this change has broken pipenv for my projects!

Same, this was a breaking change in a patch version.

Likewise broke all the builds. Looks like issue identified and fixed in pull request. Lets hope it gets merged into master and built asap

Introduced in #1855, which was merged without review and with nearly all checks failing.

Should we merge the fix without a review then? ;)

when can we know if it gets fixed, and how can i download the new version? im trying to do a virtualenv project but i get the same error

Use pip install virtualenv==20.0.21 to return to the previous version.

Another confirmation of breakage from me. It broke all of my production build pipelines.

I have the same issue

anybody fixed it ?

I want to blame pipenv for failing to freeze its dependencies but that was a patch version (still, pipenv should freeze its dependencies)

Can we just rename PythonActivator to PestythonActivator? That just sounds better IMO

pip uninstall virtualenv==20.0.22
pip install virtualenv==20.0.21

it is ok for now for me

Use pip install virtualenv==20.0.21 to return to the previous version.

To future-proof, I'd recommend pip install 'virtualenv!=20.0.22'.

the reply from joekohlsdorf helps a lot

pip uninstall virtualenv==20.0.22
pip install virtualenv==20.0.21

My broken built is on the Travis side, it runs tox, is there a way to pin the virtualenv version in that case?

Seems the devs fixed it now, panic over.

So sorry, messed up that release earlier (🤦), should be all fine now with 20.0.23.

Version 20.0.23 works fine :+1:

"leftpad grade issue" :-(

ahh, the irony.
