Pytest Version Conflict Error
debian, pytest, python
Solution
The files in `/usr/local/lib/python2.7/dist-packages` belong to python packages you installed with pip, easy_install or `python setup.py`. The system update probably messed up some dependencies. Does this work?
sudo apt-get install python-pip
sudo /usr/bin/pip install -U pytest
Problem
After update of Debian (Jessie), pytest doesn't work : ``` #py.test Traceback (most recent call last): File "/usr/bin/py.test", line 5, in <module> sys.exit(load_entry_point('pytest==2.4.2', 'console_scripts', 'py.test')()) File "/usr/local/lib/python2.7/dist-packages/pkg_resources.py", line 348, in load_entry_point return get_distribution(dist).load_entry_point(group, name) File "/usr/local/lib/python2.7/dist-packages/pkg_resources.py", line 2311, in load_entry_point return ep.load() File "/usr/local/lib/python2.7/dist-packages/pkg_resources.py", line 2024, in load if require: self.require(env, installer) File "/usr/local/lib/python2.7/dist-packages/pkg_resources.py", line 2037, in require working_set.resolve(self.dist.requires(self.extras),env,installer))) File "/usr/local/lib/python2.7/dist-packages/pkg_resources.py", line 571, in resolve raise VersionConflict(dist,req) # XXX put more info here pkg_resources.VersionConflict: (py 1.4.15 (/usr/lib/python2.7/dist-packages), Requirement.parse('py>=1.4.17')) ``` How can I fix this error? Thanx in advance!
