Description
Type: Bug
Behaviour
The integrated terminal in VS Code Insiders does not activate the selected Python 3.12.10 environment. Instead, it defaults to the system-wide Python 3.11.12 installation.
- VS Code Insiders status bar correctly shows "Python 3.12.10" and hovering shows the path to the 3.12.10 executable (e.g., C:\Users\Kumar\AppData\Local\Programs\Python\Python312\python.exe).
- However, running commands in the integrated terminal shows:
python --versionoutputs:Python 3.11.12python -c "import sys; print(sys.executable)"outputs:C:\Users\Kumar\AppData\Local\Programs\Python\Python311\python.exe(the path to the 3.11.12 executable).
Steps to reproduce:
- Open VS Code Insiders with a Python project/file.
- Ensure Python 3.12.10 interpreter is selected for the workspace/user (verified by status bar hover).
- Ensure "python.terminal.activateEnvironment": true is set in User Settings.
- Open a new Integrated Terminal (e.g., PowerShell).
- Run
python --versionandpython -c "import sys; print(sys.executable)".
Expected behaviour
The integrated terminal in VS Code Insiders should activate the selected Python 3.12.10 environment. Running python --version and python -c "import sys; print(sys.executable)" in the Insiders terminal should report Python 3.12.10 and the path to its executable.
Diagnostic data
Output for Python in the Output panel (View→Output, change the drop-down the upper-right of the Output panel to Python)
Checked the "Python" output channel as requested, but it contained no log output related to the issue during reproduction steps, or the channel was not available in the dropdown list (despite python extensions installed properly).
