Missing dependencies for fts-rest-cli

[daikema]

When attempting to install the UMD-packaged version of fts-rest-cli into singularity container (found in this repo I hit upon some missing dependencies when attempting to run the client.

fts-rest-transfer-submit --help
Traceback (most recent call last):
  File "/bin/fts-rest-transfer-submit", line 2, in <module>
    from fts3.cli import JobSubmitter
  File "/usr/lib/python2.7/site-packages/fts3/__init__.py", line 1, in <module>
    import pkg_resources
ImportError: No module named pkg_resources

This first error was resolved by adding the python-setuptools package to the container build def.
Following that a second error was also encountered:

fts-rest-transfer-submit --help
Traceback (most recent call last):
  File "/bin/fts-rest-transfer-submit", line 2, in <module>
    from fts3.cli import JobSubmitter

ImportError: No module named certifi

I didn't notice any package available via yum which would resolve this missing dependency issue so for the moment I'm installing this via pip in the container def file.

Thanks @daikema ! I'll take a look and see if I can reproduce and fix. This fix will probably come in in a separate role or channel but you'll also be notified her.

I discovered that the requests package was being pulled from my home directory as when I ran as another user I hit the following error:

Traceback (most recent call last):
  File "/bin/fts-rest-transfer-list", line 2, in <module>
    from fts3.cli import JobLister
  File "/usr/lib/python2.7/site-packages/fts3/cli/__init__.py", line 18, in <module>
    from banning import Banning
  File "/usr/lib/python2.7/site-packages/fts3/cli/banning.py", line 18, in <module>
    from base import Base
  File "/usr/lib/python2.7/site-packages/fts3/cli/base.py", line 25, in <module>
    from fts3.rest.client import Context
  File "/usr/lib/python2.7/site-packages/fts3/rest/client/__init__.py", line 19, in <module>
    from context import Context
  File "/usr/lib/python2.7/site-packages/fts3/rest/client/context.py", line 36, in <module>
    from request import Request
  File "/usr/lib/python2.7/site-packages/fts3/rest/client/request.py", line 20, in <module>
    import requests
ImportError: No module named requests

Installing the python2-requests package resolved this issue.
