Here are the c++ reditribute installed at my pc

Answer 1

Currently, pyodbc on PiPI (pyodbc 4.0.27) does not have wheel files for Python 3.8, so when you do pip install pyodbc pip will try to build pyodbc from source. You don't need C++ redistributables for that, you need a C++ compiler .

The next release of pyodbc will almost certainly have pre-compiled wheel files for Python 3.8. In the meantime you can download the required wheel file from

https://www.lfd.uci.edu/~gohlke/pythonlibs/#pyodbc

and then install it with

pip install C:\path\to\pyodbc-4.0.27-cp38-cp38-win32.whl

Update 2020-06-30: Current versions of pyodbc now have wheels for Python 3.8.

Thank you very much. I was using Python 3.10. This did the trick.
