Question

Running pip na OSX daje następujący błąd:

Traceback (most recent call last): 
    File "/usr/local/bin/pip", line 9, in <module> 
    load_entry_point('pip==6.0.6', 'console_scripts', 'pip')()

    raise ImportError("No module named '%s'" % (name,)) 
ImportError: No module named 'pip._vendor.cachecontrol'
