I'm using Python 3.8 and pip 19.3.1 on Windows 10 and when I try to pip install email I get an error:

    ERROR: Command errored out with exit status 1:

How do I get this module installed?

Answer 1

The email module was distributed for pythons 2.3 and 2.4. Starting with 2.5, it was included in the standard python distribution. You're looking for https://docs.python.org/3/library/email.html

Answer 2

Module 'email' is deprecated and no longer being updated. It was last updated on Jul 19, 2011. Latest version of python at that time was Python 2.7

So, it doesn't support Python 3.8. What you can do is install it in Python 2.7

Use the following command to install version 6.0.0 in Python 2.7

pip install email==6.0.0a1
