I use Cmder on windows 10 with Python 3.5 and virtualenv on my laptop and work computer just fine.
Now I have a new computer running Windows 10, Python 3.5, virtualenv 15.0 and I am able to initialize a python virtual environment with:
and I get the virtualenv directories but when I run:
Nothing happens. No error message and worst of all nothing to signify that the environment was activated or not (i.e. the string "(env)" does not pop up in the terminal next to the path).
The odd thing is that I can activate a venv when using plain old cmd and the "(env)" shows up in the terminal. Just not when run in Cmder. Another oddity (which I don't think is related but may be) is that once I can get a virtualenv running in regular cmd, it says the "deactivate" keyword is not recognized when I try to shut it off.
I found this post (below) on StackOverflow which is similar but not all that useful as it doesn't actually have an answer and is more about PowerShell.
