Create virtual environment permanently fails when Base interpreter is Python 3.8

Describe the bug After I open a Solution with requirements.txt in its dir Visual Studio detects it and shows a badge with the “Create virtual environment” link. I click it, change env to venv and click “Create”: After a few seconds process finishes with conflicting messages between “Background tasks” window and “Output” window:

Steps to Reproduce

1. Create some Python Solution.
2. Place requirements.txt into its dir so VS can detect it.
3. Save and reopen the Solution in VS.
4. Continue as described in “Describe the bug” section above.

Expected behavior A successfully created Python Virtual Environment.

Configuration information (If you are providing a diagnostics file (see below), skip this section) VS Version: 16.5.3 PTVS version: 16.5.20041.1-16.0 Python version: 3.8

Thanks for the info. It worked for me. Then I noticed that your Python 3.8 is the Windows Store install and mine was the python.org install. We’ll have to try this again with the store version.

@LyonsDo can you please file a new bug, include details on which base environment you are using when creating the virtual env and attach the diagnostics (see instructions in the bug template). Thanks!
