I am trying pip install psycopg2
in vscode cmd on windows 8.1, which results in the following error.
ERROR: Command errored out with exit status 1:

The solution is in the error message. You need the Visual C++ runtime installed. Go to
https://support.microsoft.com/en-gb/help/2977003/the-latest-supported-visual-c-downloads
and download the version appropriate to your system, then install and try again.
The error message is misleading in this case. It's an issue with psycopg, it doesn't appear to support Python 3.8 on Windows yet. Solution is to use 3.7 until psycopg is ready.
