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

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.
