Cannot select 2.7 as interpreter #20637

@phantasm

Description

@phantasm

Type: Bug

Behaviour

Expected vs. Actual

Expected: select Python 2.7.18 interpreter from drop-down list (via browsing)

Actual: nothing happens and yellow button "Select interpreter" is still displayed in the status bar. Latest vscode-python version which works fine is 2022.18.2. Any recent version have this bug. I didn't notice any warnings about dropping 2.7 completely in release notes, and hope it won't happen :)

Steps to reproduce:

Try to select Python 2.7.18 interpreter from drop-down list - browse to its folder and select python.exe

Diagnostic data

  • Python version (& distribution if applicable, e.g. Anaconda): 2.7.18
  • Type of virtual environment used (e.g. conda, venv, virtualenv, etc.): Unknown
  • Value of the python.languageServer setting: Default
Output for Python in the Output panel (ViewOutput, change the drop-down the upper-right of the Output panel to Python)
