Failed to update camp: "error in camp setup command"

Characteristics

• Issue Type: bug
• Reproducibility: always
• Severity: block
• Tool/Service/Component: CAMP, 0.3.4
• Execution Environment: vmi2.stamp-project.eu, Debian Jessie, amd64
• Reporter: Daniele Gagliardi, daniele.gagliardi@eng.it

Description

I tried to update CAMP installation within STAMP CI/CD server (vmi2.stamp-project.eu), using pip to update it, but I got following error:

    Complete output from command python setup.py egg_info:
    error in camp setup command: 'install_requires' must be a string or list of strings containing valid project/version requirement specifiers
    
    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-req-build-zGl9AM/

The worst thing is that now camp is no longer working (and the Lutece Jenkins pipeline doesn't work anymore). If I type:
camp -h
I get following error:

Traceback (most recent call last):
  File "/usr/local/bin/camp", line 6, in <module>
    from camp.run import main
ImportError: No module named camp.run

Steps to reproduce

As root user:

• After login, I went to camp project cloned a month ago:
  cd camp
• Then I update camp repo:
  git pull
• Then I performed installation as I did last time:
  pip install -e .

I tried also, after removing camp folder, to update it launching following command:
pip install -U git+https://github.com/STAMP-project/camp.git@master#egg=camp

The output is quite similar:

Collecting camp from git+https://github.com/STAMP-project/camp.git@master#egg=camp
  Cloning https://github.com/STAMP-project/camp.git (to revision master) to /tmp/pip-install-kG_3I6/camp
    Complete output from command python setup.py egg_info:
    error in camp setup command: 'install_requires' must be a string or list of strings containing valid project/version requirement specifiers
    
    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-install-kG_3I6/camp/

I have had issues with PIP versions earlier than 19.0.3, which seem to not support the "git+url" syntax.
Which version are you using?

[danzone]

Ops, I missed your comment: pip version was 19.0.3. Today I updated it and now it is at version 19.1. But the error remains the same. When I launch the command:
stamp@vmi2:~/stamp-assets/camp$ sudo pip install -e .
the output is:

DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date. A future version of pip will drop support for Python 2.7.

I haven't succeed to reproduce this error. Here is the commands I run:

$ virtualenv -p /usr/bin/python3.5 .py3.5
$ source .py3.5/bin/activate
$ git pull --branch=v0.3.4 https://github.com/STAMP-project/camp.git
$ cd camp
$ pip install -e .
$ git checkout tags/v0.4.0
$ pip install -e .

Do you see anything you'd have done differently? Do you remember which version you tried to upgrade to?
