New submission from wolfgang kuehn <[email protected]>:
I just installed Python3.10.1 from the Windows 10 App Store.
Most workflows depend on creating virtual environments, but (1)
python -m venv venv
# -> Error 1260: Windows cannot open this program because it has been
prevented by a software restriction policy
However, a (2)
python -m venv --without-pip venv
completes, only to not allow execution of (3)
.\venv\Scripts\python.exe
# -> Error 1260: Windows cannot open this program because it has been
prevented by a software restriction policy
Reason for this probably are the (not so unreasonable) cooperate Software
Restriction Policy (in our case enforced by Applocker):
You are not allowed to execute from where you are allowed to write.
So basically Python is broken in many MS Windows cooperate settings. Cooperate
meaning (Software Restriction Policies) + (Usage of Virtual Environments).
And my feeling is that it does not need to be, the virtual environment
implementation with those *.exe copies being a kludge, IMHO.
Note: (2) is reminiscent of bpo-45337, which was fixed with 3.9.
