Whenever i try to use pip I get an error. For exampple:
$ sudo pip install gevent-websocket Traceback (most recent call last): File "/usr/local/bin/pip", line 5, in <module> from pkg_resources import load_entry_point File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 2675, in <module> parse_requirements(__requires__), Environment() File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 552, in resolve raise DistributionNotFound(req) pkg_resources.DistributionNotFound: pip==0.8.1
I feel tempted to change the value of into pip==0.8.2.. but I dont feel dealing with the consequences of 'hacking' up my installation... I'm running python 2.7 and pip is at version 0.8.2.
I find this problem in my MacBook, the reason is because as @Stephan said, I use
easy_install to install pip, and the mixture of both py package manage tools led to the
The resolve is:
easy_install --upgrade pip
Remember: just use one of the above tools to manage your Py packages.
I replaced 0.8.1 in 0.8.2 in /usr/local/bin/pip and everything worked again.
__requires__ = 'pip==0.8.2' import sys from pkg_resources import load_entry_point if __name__ == '__main__': sys.exit( load_entry_point('pip==0.8.2', 'console_scripts', 'pip')() )
I installed pip through easy_install which probably caused me this headache. I think this is how you should do it nowadays..
$ sudo apt-get install python-pip python-dev build-essential $ sudo pip install --upgrade pip $ sudo pip install --upgrade virtualenv
