Django Nose Tests Failing - Traceback from Nose Code

Question

I am unable to run django nose tests, all processes fail with this traceback:

Traceback (most recent call last):
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/multiprocessing/process.py", line 258, in _bootstrap

Here are the relevant bits from pip freeze :

Django==1.5.1
MySQL-python==1.2.5
South==0.7.6
Werkzeug==0.8.3
boto==2.8.0
dj-database-url==0.2.1
django-appconf==0.6
django-compressor==1.2
django-extensions==1.0.3
django-json-field==0.5.5
django-nose==1.1
django-storages==1.1.6
django-waffle==0.9.0
djangorestframework==2.1.17
nose==1.3.1

Anyone else seen this? I've seen it mentioned in this pull request ( https://github.com/nose-devs/nose/pull/710 ) but not clear what the solution was.

Answer 1

I just went into the nose source code and commented out lines 156-158.

    #self.coverInstance.exclude('#pragma[: ]+[nN][oO] [cC][oO][vV][eE][rR]')
    #self.coverInstance.load()
    #self.coverInstance.start()

All my tests run fine now. O_o
