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:
- Make sure this message is at the bottom of the installation messages, as much as possible.
- Use console colors (is this possible on Windows?)
- Use capital letters. (If Improve caching code #2 doesn't work.)
- 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.
