Can't install on linux following tutorial in README

[HMaker]

I tried to install htm.core following installation tutorial with pip:

$ pip install -i https://test.pypi.org/simple/ htm.core
Looking in indexes: https://test.pypi.org/simple/
Collecting htm.core
  Downloading https://test-files.pythonhosted.org/packages/db/71/6ab3ea6b98e3de12d43387a590f922917e9dfab08147000b8fdef1aa86ae/htm.core-2.1.15-cp37-cp37m-manylinux2014_x86_64.whl (6.5 MB)

ERROR: Could not find a version that satisfies the requirement mock>=1.0.1 (from htm.core) (from versions: none)
ERROR: No matching distribution found for mock>=1.0.1 (from htm.core)

I think it happened because it's on test index. Why it's not hosted on main index, pypi.org?
I was able to install by downloading wheel file then installing it without setting index to test.pypi.org:

$ wget https://test-files.pythonhosted.org/packages/db/71/6ab3ea6b98e3de12d43387a590f922917e9dfab08147000b8fdef1aa86ae/htm.core-2.1.15-cp37-cp37m-manylinux2014_x86_64.whl
$ pip install htm.core-2.1.15-cp37-cp37m-manylinux2014_x86_64.whl

Also there is no distribution for Python 3.8 on pypi. But #820 did not solved it?

I am on Ubuntu 18.04. Thanks.

If you want to use htm.core from Python, the easiest method is to install from PyPI
Note: to install from pip you'll need Python 3.7+
python -m pip install -i https://test.pypi.org/simple/ htm.core

Does "Python 3.7+" means "Python >= 3.7"? If yes I think it's misleading since there is only distribution for Python 3.7 on pypi.

I believe the pip install is not working at the moment. I had to follow the directions to install from source.

It works, the problem is that htm.core distribution is hosted on test repository of pypi (test.pypi.org), then pip will try to search dependencies there if you pass -i https://test.pypi.org/simple/, the workaround for that is download wheel file (htm.core-2.1.15-cp37-cp37m-manylinux2014_x86_64.whl) then install it.

#943 is going forward on this issue.
