Please help to check it! Thanks!

@truongan012 What is the value of sys.executable for the case you have? it seems like it might be failing to find the executable. can you try running the python with this:

C:\msys64\ucrt64\bin\python3.12.exe -c "import sys;print(sys.executable)"

[truongan012]

Hi @karthiknadig,
It is,

-->  C:\msys64\ucrt64\bin\python3.12.exe -c "import sys;print(sys.executable)"
C:\msys64\ucrt64\bin\python3.12.exe

[karthiknadig]

@truongan012 Thanks for checking that. Can you verify the following for me?

1. Does this path exists C:\Users\ltan\Workspaces\PythonServerTest\.venv\Scripts\python.exe
2. What do you get if you run: C:\Users\ltan\Workspaces\PythonServerTest\.venv\Scripts\python.exe -m pip install --upgrade pip

If the path does NOT exist, can you share where the python.exe is under C:\Users\ltan\Workspaces\PythonServerTest\.venv

[truongan012]

Hi,
No, here it is

Result I run with that path

C:\Users\ltan\Workspaces\PythonServerTest\.venv\bin\python.exe -m pip install --upgrade pip    
Requirement already satisfied: pip in c:\users\ltan\workspaces\pythonservertest\.venv\lib\python3.12\site-packages (25.0)

@truongan012 I see it uses bin, thanks for this detail.

@DonJayamanne This might be useful bit of detail about MSYS/UCRT python. On windows they use bin instead of Scripts directory.
