@ruiztulio @JesusZapata
I think that this change will fix the current travis issue

[ruiztulio]

@moylop260 I already tested this and didn't work because there is another dependency that is updating the setuptools package later:

My guess is that wstools is installing it:

and that keep braking the build, but that's a wild guess

[JesusZapata]

@moylop260 @ruiztulio I made the test and it works good

Only add in ${REPO_REQUIREMENTS}/linit_hook/travis/requirements.txt
setuptools==33.1.1

Ran this command
pip install --no-binary pycparser -r ${REPO_REQUIREMENTS}/linit_hook/travis/requirements.txt

Are you talking about odoo-shippable right?

That was fixed from #189
Now we have the build success from https://hub.docker.com/r/vauxoo/odoo-80-image-shippable-auto/builds

Now we need a similar patch for https://hub.docker.com/r/vauxoo/odoo-80-image/ to fix the red build too (this pr try fix it the last one)

@ruiztulio
