[v5.6.2] `AttributeError: module 'subprocess' has no attribute '_ENV'`

[pdelre]

Recently released 5.6.2 (pipx installation, MacOS 12.5.1) is throwing an error for commands. From my memory, this was not occuring with 5.6.1.

$ mpm --version
mpm, version 5.6.2

Yes, that's my mistake. I just fix this in click-extra v3.2.4, which is being built and released by GitHub CI jobs right now. The fix should hit PyPi in a couple of minutes. In which cas an upgrade of this dependency will fix the issue. I even thinking of releasing a new mpm in a couple of hours.

Thanks for the quick response.

For anyone else, I was able to resolve for now with pipx (I thought other 5.6.x was working yesterday, but they all were failing today so dropping back to 5.5.1)

pipx install --force meta-package-manager==5.5.1

[kdeldycke]

Thanks @pdelre for the pipx command. It should help others use mpm in the mean time. I'll release mpm v5.7.0 in a couple of hours or tomorrow, the 5.6.x has been plagued with other broken dependencies.
