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

[Joe Pluta <joepluta@xxxxxxxxxxxxxxxxx>]

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!
