[vscode ver. 1.100] Python environment incorrectly activated #25051

Python environment incorrectly activated

It was working fine in version 1.99

But now when I launch a new integrated terminal, I can see the usual indicator for loaded python environment (environment name between parenthesis at the start of the terminal prompt), but typing "python" in the terminal produces the following:

$ python
Command 'python' not found, did you mean:
  command 'python3' from deb python3
  command 'python' from deb python-is-python3

I use pyenv to manage environments and here is how it is set up in .profile and .bashrc files:

export PYENV_ROOT="/home/wsluser/.pyenv"
command -v pyenv >/dev/null || export PATH="/home/wsluser/.pyenv/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/home/wsluser:/home/wsluser/.local/bin"
eval "$(/home/wsluser/.pyenv/bin/pyenv init -)"

Shell seems correctly set up as I compared $PATH variable in the Integrated terminal and the standalone.

It looks like pyenv settings are not applied to the integrated terminal session.

Please note the following:

  • in a standalone terminal, switching environments works well
  • it works well in version 1.99 (I have two machines. Had the issue on the first one first (Windows) with version 1.100. The second one (Mac) with version 1.99 was working fine until it was updated with 1.100)
