Thank you you @ria18405 for the PR. Can you improve the commit description by adding some text about the files modified?

The test for Python 3.5 are failing due to this error:

      File "/home/travis/virtualenv/python3.5.6/lib/python3.5/site-packages/setuptools/sandbox.py", line 195, in setup_context
        yield

      File "/home/travis/virtualenv/python3.5.6/lib/python3.5/site-packages/setuptools/sandbox.py", line 44, in _execfile
        code = compile(script, filename, 'exec')
      File "/tmp/easy_install-9qmvxszx/pandoc-2.0a4/setup.py", line 11
        error = f"pip is not installed, refer to <{url}> for instructions."

    SyntaxError: invalid syntax

Can you have a look at this problem?
It may be due to the way Python is installed, since in tests for Python 3.6 no errors are thrown (see below).

Hi @valeriocos ,

I could not generate this error on my local machine.

• For 'pip not installed', I downloaded and set up a python3.5 virtual environment with pip version pip 20.0.2 from /home/ria/venv3.5/lib/python3.5/site-packages/pip (python 3.5)
• For failure of python setup.py egg_info", I upgraded setuptools.
• While running pip install . I get a successful build message :

Successfully built perceval
Installing collected packages: perceval
Successfully installed perceval-0.13.0

What could be the problem?

[valeriocos]

Hi @ria18405 ,

Maybe it's the pip version, in python 3.6 is pip 19.0.3 and no errors are thrown, while for python is pip 18.1 and there are errors.

Try to repeat what you did here #641 (comment), but using that pip version. If the error appears, you can create a new PR that modifies the before_install section to upgrade the pip version.

Thanks!

Hi @valeriocos
Upgrading the pip version didnt help in the travis tests for python3.5. Although again, locally I'm getting a successful installation, and all tests run perfectly - Ran 956 tests in 151.722s. What can I do to resolve this?

[valeriocos]

Hi @ria18405, the same error appears also on this PR: chaoss/grimoirelab-elk#833.

Can you work together with @animeshk08 to solve it?

[animeshk08]

Sure @valeriocos I am on it!

[valeriocos]

Thanks!

Hi @ria18405. try upgrading setup tools in travis.yml. Add the below line to before_install section:
pip install --upgrade setuptools

I am not quite sure why this has happened but based on a bit of hunch and this answer I believe the trouble was with linking of setup tools with pip. Sorry, I could not find a good reference. Let me know how it goes :)

Hi @animeshk08

Thanks for the suggestion, I stumbled on a similar reference earlier and upgraded setuptools in my local tests, but didn't add it in travis.yml. I'll try to follow that. Hope it works! Thanks :)

Hi @valeriocos
The PR is ready for review.
Thanks

[valeriocos]

Thank you @ria18405 , can you rebase your PR, the branch isn't aligned with master.

If upstream is the original repo https://github.com/chaoss/grimoirelab-perceval, you can do:

git fetch upstream
git rebase upstream/master
