  • Take a look at the same issue [here](https://stackoverflow.com/questions/44951456/pip-error-microsoft-visual-c-14-0-is-required). – Sadra Sabouri Sep 25 '21 at 09:46
  • @SadraSabouri thank you, I "Modify" installation to include the Visual C++ build tools and run: pip install --upgrade setuptools. After restarting the machine then it works. – Tom Tran Sep 25 '21 at 11:28
