Imports in egg installations broken with commit 34337de

[marcharper]

Python 2.7.9 (ubuntu)

The gitinspector_0.4.2-1_all.deb release works fine but the latest master (installed with sudo python setup.py install generates the following traceback:

user@tower:~/repos/axelrod/Axelrod$ gitinspector -F text

Hi & thanks for the report.

I am aware of this. The error is related to commit 34337de.

It's related to the base path pointing differently in an egg installation. I'll take a closer look eventually. Currently, I'm not quite sure what the best solution is.

[adam-waldenberg]

Done. This should now be resolved. Please report any problems related to this here.

[adam-waldenberg]

Hm.. Interesting ... Could you print out your sys.path right before each import ? Something like;

print(sys.path)

Hopefully that can help me track down whats going on.

I'm also running into this... Don't know if this will help but I'll give you the steps I took:
Cloned repo (added the print commands before import ouputable in gitinspector.py and before import format in outputable.py)

$ cd gitinspector
$ sudo python setup.py install
$ gitinspector #works so long as I only run it inside the gitinspector dir that I cloned
$ cd /some/project
$ gitinspector

    import format
ImportError: No module named format

If I fully qualify the import name (import gitinspector.format) it seems to work on that one and dies on the next:

I think there is some confusion about how imports are searched for in python.(This stack overflow thread may help.)

In this case the imports need to be relative. Python doesn't search the local module for imports once installed. Adding "gitinspector" to the system path doesn't solve the issue because the subfiles (like format.py) are not modules. To be fair, it is all a bit confusing, and the error from the traceback is not very helpful. It also doesn't help that the imports work locally (since python searches the local directory first).

You also might consider following the PEP 8 import conventions.

I just opened a pull-request to fix the issue.
