Re: [IBMiOSS] Python, ACS, Open Source and MKDocs -- OPENSOURCE

Can any of the Python experts on the list here please tell me what this means?

Specifically this:

File "/QOpenSys/pkgs/lib/python3.6/site-packages/pkg_resources/__init__.py", line 860, in resolve
raise VersionConflict(dist, req).with_context(dependent_req)
pkg_resources.ContextualVersionConflict: (tornado 6.1 (/QOpenSys/pkgs/lib/python3.6/site-packages), Requirement.parse('tornado<6'), {'livereload'})

If I read this correctly, it looks like there is a requirement definition somewhere specifying that I must have a tornado package whose release is less than 6. This won't work because I have tornado 6.1, the latest. This conflict does NOT occur in my Ubuntu installation, and MKDocs runs happily. So this raises a few questions:

1. Am I correct, is this a requirement that the tornado release be <6?
2. Where are these requirements defined? I've been scanning directories and I can't find it.
3. Why would the requirement be LESS THAN 6? I understand AT LEAST n.n, but less than?

Help here is needed. I've been using Google-Foo and it's really hard to find anything on Python dependencies.

Thanks!

I continue to make progress, but this one looks a little difficult. At the very end, it says I have a resource conflict and that looks as though my version of tornado is 6.1, but the program expects it to be less than 6. At least that's what the messages seems to be saying. The problem is that I don't know why it needs to be less than 6, nor do I know where tornado is nor whether it's something can fix.

I take back one small part of that - tornado lives in the python3.6 site-packages folder. I still, however, don't know what to do. :)

And please note, I am NOT using a venv. I have set my PATH as suggested using my .bashrc file and everything seems to be working.
