markupsafe silently failing on amazon linux

[dsadinoff]

[cross-posted from SO: http://stackoverflow.com/questions/34554471/markupsafe-wont-install-in-virtualenv-on-amazon-linux ]

I find that MarkupSafe installs fine in the main machine environment, but in a virutalenv, pip silently fails.

Is there more I ought to do to help debug this?

Hmm, I couldn't reproduce locally. Tested with both a Python 2 & 3 virtualenv.

[dsadinoff]

Ivoz, can you confirm that that was running on Amazon Linux?

[pfmoore]

@dsadinoff This looks like something specific to Amazon Linux. And markupsafe's setup.py does some fancy things to test-build a C extension. Could you run pip install markupsafe -v to get the full log of the install?

I suspect markupsafe's setup.py is failing somehow, but isn't correctly setting its exit status so that pip notices the failure. But that's just speculation, let's see the full log first :-)

[dsadinoff]

here you go:

Bah. That still didn't show the output of setup.py install. Would you mind trying again with -vvv (to get maximum level logging)? My apologies, I should have asked for this originally.

[Ivoz]

I just ran locally on ArchLinux.

It's actually surprising that pip installed markupsafe twice, from your initial paste. It should normally say that the requirement is already satisfied.

[jurov]

It is reproducible on amazon linux 2015.09 where I encountered same problem installing twisted, see my comment on SO. Amazon Linux installs virtualenv-12.0.7 by default, I fixed it by installing latest 15.0.0.

[Atheros1]

I was able to solve this by using the 64bit Amazon Linux 2016.03 v2.1.0 AMI. Also, since I had replaced the default wsgi.conf with one that I made changes to, it was critical that I got the original wsgi.conf for this AMI and made my customizations to it rather than continuing to use the customized wsgi.conf that I was using for the previous AMI.

[Atala]

Same for me, upgrading virtualenv from 12.0.7 to 15.0.0 did the trick.

@pfmoore vvv output with virtualenv 12.0.7

Cleaning up..

Looks like an old version of pip, as it's doing setup.py install. New versions do setup.py wheel then install the wheel.

I'd be inclined to write this off as a quirk of old behaviour of "something" (pip, setuptools?) and say that upgrading is the fix, unless anyone hits it with a current version of pip.

[Atala]

Agree, virtualenv 12.07 uses pip 6.0.8 and virtualenv 15.1.0 uses pip 9.0.1

[dsadinoff]

Yup, looks fine for me now as well. looks like the various tools "grew out" of the bug. thanks!

We're still getting this same issue on Amazon Linux for MarkupSafe. Any workaround?

[wiredfool]

I'm seeing this on several compiled extensions on AmazonLinux 2.8.0, so I don't think that this is specific to markupsafe. See here for workaround: #1117 (comment)
