VSCode isn't involved in installing packages. I would open up a shell (not in vscode), activate the venv, and do pip install from the shell. Does it work?

Is the same OS in both cases? Is it the same machine? I've had wheels fail because I didn't have all the required tools installed and all the correct paths defined.

It is the same machine, the same Windows

You can open shell within VSCode, but that won't help in this instance.

The problem here, is that the package does not use pip.
It is a driver, and as must be downloaded by clicking on the download link.
Then extracted and installed. Unless you can find a wheel for the package.

Does not work. Again the same info on the screen

(.venv) C:\Roboczy\Python37Venv>py -m pip install C:/users/zdzis/Downloads/ibm_db-3.1.3.tar.gz

Examaple from start make an enviroment and give it name(this make easier to an avoid conflicts).

Make file in this folder ibm_test.py

print(ibm_db_dbi.Connection)
print(ibm_db_dbi.__version__)

Start Vs Code from this folder(keep envioment active) using code . the it will find virtual enviroment in the list.

What do you have in environment var paths ? I feel that is the key to that puzzle :)

No,virtual environment don't use OS environment path at all.
The virtual environment environment variable is only available if the virtual environment is activated.
The point of me doing the the first post was so you could do the same from command line.
I use cmder,but commands is just the same in cmd or PowerShell.

I have Python 3.10 set as OS environment variable.

If i activate ibm_env it will use the Path in this folde,and environment path is not used.
