Hello,

I’ve been attempting to install Hail for the past few hours and I just can’t seem to get it to work.  
I have so far tried re-downloading Java have used both Python 3.8 and Python 3.7, and I just keep encountering roadblocks. When using Python 3.7, using “pip install hail” results in this block of error text:

When I try with Python 3.8 installed, I can pip install Hail, but I can’t import it into Python. Here’s what happens when I try:

I am incredibly stumped. Can someone help me through this? Which version of Python should I be using, and how do I get it to agree with Hail and its dependents?

Hail isn’t known to work (or even install!) on Windows. I think your best bet is to use Docker, as described here:

> @ozyurtf, regarding a GNU/Linux VM, I recommend investigating Docker for Windows. It makes it easy and quick to run GNU/Linux on Windows. You can use [this Dockerfile](https://github.com/danking/docker-hail/blob/master/Dockerfile). If you’ve never used Docker before, you should check out the [Docker orientation and set up](https://docs.docker.com/get-started/). If you want to use Jupyter Notebooks, you’ll need a Dockerfile for Jupyter Notebooks. Be sure to update the hail version to the latest version!

Saw this same PySpark installation error on Linux in a GitHub Actions workflow and was able to resolve it by installing [wheel](https://pypi.org/project/wheel/).
