can't find '_main_' module in 'superset'

Hello @eschutho @craig-rueda @hughhhh @michael-s-molina
When I want to run the Superset project directly from the github project instead of installing it in virtualenv, I get the following error.
Error Description: can't find 'main' module in 'superset'

Heya... curious about a few things here:

1. Is there a reason not to use virtualenv? That's still one of the key steps to avoid python package issues when installing the project... even when it's straight from the github project as you mention.
2. Is there anything in particular you're doing, procedurally, that we should be aware of to reproduce such an issue, other than skipping those instructions?
3. Would the docker installation be more useful if you can't use a virtualenv for some reason?
4. What kind of machine / OS / python version setup are you running?
5. What version of Superset are you running?

I don't quite feel like we can call this a community bug until we know more.

Thanks for your answer. I'm working with python 3.8 on a windows machine and I want to install locally instead of docker. However, "gunicorn" used as an application server does not work for windows, can an alternative such as "waitress" be used instead?

Sounds like this is intrinsically tied with #22922 - I assume you're working together. Can we close one of these duplicate issues?

As I mentioned on the other thread, @Indows is not officially supported, but you can ask around in the #deploying-superset channel on Slack, or start a Q&A Discussion here on the repo look for anyone else attempting this.

Similar issue but I haven't tried running it with a different application server yet. I will follow up on this issue as well. For now, I'm looking at the installation process from source.
