Summary

A number of users are running into trouble installing Streamlit on Windows because they don't realize they have to manually edit their $PATH.

Solution 1

Set the $PATH automatically after installation on Windows.

Solution 2

If Solution 1 is impossible for some reason, then we could increase the discoverability of the message to set the $PATH on Windows, following this suggestion.

Ways to make it stand out:

1. Make sure this message is at the bottom of the installation messages, as much as possible.
2. Use console colors (is this possible on Windows?)
3. Use capital letters. (If Improve caching code #2 doesn't work.)
4. Separate this message from others with a newline above and below.

We don't need to do all of these options, but it'd be nice to have the minimum to improve discoverability.
