Virtualenv Name Incorrect When Activated with Powershell Script

[Anti-Distinctlyminty]

Issue

When using the Activate.ps1 script, the name in parenthesis becomes (activate.ps1), as opposed to the name of the virtual environment when using the bat file.

Environment

Provide at least:

• OS: Windows Build 19042.906
• pip list of the host python where virtualenv is installed:

A PR fixing this would be appreciated.

Hello - Is this error specific to OP's environment and his packages installed in the environment? I tried creating a new virtualenv and didn't see the issue. Both cmd's activate and powershell's activate show the correct virtualenv name.

[Anti-Distinctlyminty]

Odd. I am no longer seeing it. I shall reopen if I can reproduce.

[Anti-Distinctlyminty]

I've ended up back here again.
Again it does seem to be something to do with UNC paths. I've created a virual environment on a network drive.
To reproduce:

In powershell navigate to some network location using a mapped drive and create the virtual env:

PS > cd T:\__Tests\temp
PS T:\__Tests\temp > C:\Python27\python.exe -m virtualenv .venv -vvv

Activate it. As shown here you may have to set the execution policy

PS T:\__Tests\temp > set-executionpolicy unrestricted -scope process
PS T:\__Tests\temp > .venv\Scritps\activate

Not only is the virtualenv name incorrect, but the activation isn't actually working, it just picks up whatever python is first on path.
Checking the path environment shows why, as the injected path is clearly incorrect.
