Failed to build ciso8601 on WSL on Windows 10

Am getting the following error when trying to install Home Assistant on Windows 10 with Python 3.8. Can anyone suggest how to fix?

Building wheels for collected packages: ciso8601

Do you have gcc installed under WSL?

Ah. I hadn’t explicitly - assumed it would be a dependency. Installed it manually, re-ran it and got a missing Python library error.

I must have missed an error when installing the dependencies. I’ve run them again now and it’s built.

Thanks!

$ sudo apt install python3.9-dev

solved the same problem for me.
