ImportError: cannot import name wraps

I'm using python 2.7.6 on Ubuntu 14.04.2 LTS. I'm using mock to mock some unittests and noticing when I import mock it fails importing wraps.

Not sure if there's a different version of mock or six I should be using for it's import to work? Couldn't find any relevant answers and I'm not using virtual environments.

mock module says it's compatible with python 2.7.x: https://pypi.python.org/pypi/mock


Python 2.7.6 (default, Mar 22 2014, 22:59:56)
[GCC 4.8.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from mock import Mock
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/local/lib/python2.7/dist-packages/mock/__init__.py", line 2, in <module>
import mock.mock as _mock
File "/usr/local/lib/python2.7/dist-packages/mock/mock.py", line 68, in <module>
from six import wraps
ImportError: cannot import name wraps

also tried with sudo with no luck.

$ sudo python -c 'from six import wraps'
Traceback (most recent call last):
File "<string>", line 1, in <module>
ImportError: cannot import name wraps

Answer Source

Installed mock==1.0.1 and that worked for some reason. (shrugs)

edit: The real fix for me was to updated setuptools to the latest and it allowed me to upgrade mock and six to the latest. I was on setuptools 3.3. In my case I also had to remove said modules by hand because they were owned by OS in '/usr/local/lib/python2.7/dist-packages/'

check versions of everything

pip freeze | grep -e six -e mock
easy_install --version

Update everything

wget https://bootstrap.pypa.io/ez_setup.py -O - | sudo python
pip install mock --upgrade
pip install six --upgrade

Thanks @lifeless
