Nosetests python will not work

Question

I learned Python from "learning python the hard way," and I'm stuck in exercise 46 ( http://learnpythonthehardway.org/book/ex46.html ).

I installed pip and then the nose package and whenever I run nosetest now, as in the example, it does not work. This is the error I get:

Traceback (most recent call last): File "/usr/local/bin/nosetests", line 5, in <module> from pkg_resources import load_entry_point File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 2807, in <module> parse_requirements(__requires__), Environment() File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 594, in resolve raise DistributionNotFound(req) pkg_resources.DistributionNotFound: nose==1.3.0 

I considered this, but could not find the answer. I'm on the Lubuntu 13.04 desktop.

Answer 1

You need to install the nose version equal to 1.3.0 (maybe the installed nose version is not 1.3.0 ?)

You can find out which version of nose you installed using

 >>> import nose >>> nose.__version__ '1.3.0' 

Using pip is as simple as (if you already have nose installed, then you will want to use the --upgrade flag)

 pip install --upgrade nose==1.3.0 

or even directly from the website

 pip install -Iv https://pypi.python.org/packages/source/n/nose/nose-1.3.0.tar.gz#md5=95d6d32b9d6b029c3c65674bd9e7eabe
