Trying to install Tornado on my Win10 VS2017 for Python 3.6 64-bit using this command pip install tornado and am getting this error:

----- Installing 'pip install tornado' ----- Requirement already up-to-date: pip in c:\program files (x86)\microsoft visual studio\shared\python36_64\lib\site-packages (18.0) Collecting install Could not find a version that satisfies the requirement install (from versions: ) No matching distribution found for install ----- Failed to install 'pip install tornado' -----

I tried to also to download the Git zip and use this command pip install -Iv https://files.pythonhosted.org/packages/e6/78/6e7b5af12c12bdf38ca9bfe863fcaf53dc10430a312d0324e76c1e5ca426/tornado-5.1.1.tar.gz (as referenced here: Installing specific package versions with pip)

http://www.tornadoweb.org/en/stable/ shows

Tornado 5.x runs on Python 2.7, and 3.4+

I tried this as well pip install --user tornado as referenced here: Tornado Install Issue

All options wind up with the same eventual error: failed to install.

I'm guessing it's related to this: (from versions: ) in the error, but I am rather new to pip/python

Tried pip install -vvv … as requested by hoefling (there's more above this in the output)

    It looks like you have Python 3.6 - can you confirm that by running `pip -V`/`python -V`? If my guess is correct - what output do you get when running `pip install -vvv https://files.pythonhosted.org/packages/ab/0e/8ec7ed219cb35fffe2f2cddbfa02b47ba5d23dd9026a41b3f2bdd63cdec3/tornado-5.1.1-cp36-cp36m-win_amd64.whl`? – hoefling Sep 22 '18 at 18:32
  • @hoefling - ran the install and got a lengthy error - I edited the original to add the results (wouldn't fit here) – Carol AndorMarten Liebster Sep 22 '18 at 23:30

    Hmm, then it's either not Python 3.6 you're having, or it's not a 64bit version. What do you get when you enter `"C:\Program Files (x86)\Microsoft Visual Studio\Shared\Python36_64\python.exe" --version` and `"C:\Program Files (x86)\Microsoft Visual Studio\Shared\Python36_64\python.exe" -c "import sys; print(sys.maxsize)"`? – hoefling Sep 22 '18 at 23:42
  • @hoefling 3.6.6 and 9223372036854775807, respectively. – Carol AndorMarten Liebster Sep 23 '18 at 01:46

I re-RTM, and noticed

In addition to the requirements which will be installed automatically by pip or setup.py install, the following optional packages may be useful....

So I downloaded the stable zip, extracted and ran: "C:\Program Files (x86)\Microsoft Visual Studio\Shared\Python36_64\python.exe" setup.py install and it worked like a charm.

I'm not well versed enough in the ways of pip or python to know why this worked and the other approaches did not.
