Get a build failed message upon pip install coverage

Issue #381 duplicate
Ikuru Kanuma created an issue

Im running Debian 8 and pyton 2.7.9. Although coverage run <program> etc work extremely well, I got the following message when getting the package from pip.

Will close this immediately if it is a non issue.

    Thanks for the blazingly fast reply! (And sorry for not responding earlier!)

    It would be nice if it is clear that the 'build failed' message actually means that I do not have the prerequisite for a optional speedup.

    Perhaps a smoother path for a first timer like me, would be: 1. pip notices that python.h is not in the system 2. Notify that an optional speed up with the c module is not available. 3. Prompt the user to either -suspend installation and let the user install the Pydev package, -or proceed twith pyton installation only

    As I really do not know how pip does stuff, not sure whats actually the best though.

    Separate qustion from above: as for now if I want to get the faster version, I should get the python-dev package, remove the current installation and re-install?

    @iku000888 Sorry I didn't answer your last question, yes, getting python-dev and re-installing should work. Unfortunately, it's very difficult to build an install workflow with I'll close this issue as a duplicate of another also discussing installation issues with compiling, maybe we can get better answers there.
