"ImportError: No module named 'hypothesis.internal'"

[ianozsvald]

At the risk of having done something stupid...

I've just tried a fresh install of both master and the pypi release. In both cases (using an Anaconda environment) into IPython if I try:

In [2]: from hypothesis import falsify
...
ImportError: No module named 'hypothesis.internal'

The same occurs if I just try import hypothesis.

Looking at my site-packages after installing with pip I see files like site-packages/hypothesis/statefultesting.py, it looks like your internal directory is being removed during install?

For the master install I did a fresh checkout (python 3.4, current Anaconda, no venv) and ran python setup.py install, I had the same problem (though the files were installed to an egg rather than a directory).

For the pip install I just used pip install hypothesis.

If I install from your master using python setup.py develop then I get the internal folder (in my checked out folder), so then the imports work.

Am I missing something silly? Maybe you've not tested your installer recently?

Hmm. That's interesting. I think I fucked up the patch release. Thanks for the report. Give me a minute and I'll fix it.

Try installing the 0.2.2 release? This should fix your problem.

(I'll still need to figure out what was actually going on in there, but the internal package wasn't supposed to be in that release at all so I've just undone the changes that accidentally made it in there. Super embarrassing)

Maybe missing an init.py in internals?

No, I think I understand. the packages property of setup.py is non-recursive, so I would have to specify that hypothesis.internal is one of the installed packages as well as hypothesis. Previously hypothesis has a flat package structure so I was able to forget about this.

At any rate the 0.2.2. release solves this by getting rid of the internals package for now because it wasn't supposed to be in the 0.2.1 release at all (it's too big a change for a patch release). Does it work for you now?

[DRMacIver]

OK. I've now tested this in the 0.2.2 release and master and am pretty confident this should work correctly now. Thanks again for the report. Feel free to reopen if you're still having issues.

[ianozsvald]

Confirmed working if installed from pip, cheers :-)

[DRMacIver]

Hurrah.

The installer is now tested on travis BTW so this sort of thing shouldn't happen again.
