I was learning Python from 'learning python the hard way' and I was stuck at 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 doesn't 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>

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 googled about this but couldn't find an answer.
I am on a Lubuntu 13.04 desktop.
You need to install a version of nose equal to 1.3.0 (maybe the nose version that you installed is not 1.3.0?)
You can find out what version of nose you have installed with
>>> import nose
>>> nose.__version__
'1.3.0'
Using pip this 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 direct from the website
pip install -Iv https://pypi.python.org/packages/source/n/nose/nose-1.3.0.tar.gz#md5=95d6d32b9d6b029c3c65674bd9e7eabe

I've recently updated Python to version 3.7 from version 3.5, and made it the default in my bash shell. I've also updated pip and made sure it uses Python3.7.
Now, whenever I try to install any module using pip I get this error"
$pip3 install google

I get the same error if I try to simply run pip. This didn't happen when I was using python3.5. I did have this problem when briefly using python2.7, but I fixed it using https://askubuntu.com/questions/581999/pip-raises-importerror-cannot-import-name-httpshandler. That solution doesn't seem to work for python3.7.
I've tried to reinstall pip, reinstall python3, update my Windows Ubuntu subsystem, and reinstall libssl-dev. I'm stumped. Any help is appreciated!
You must have inadvertently upgraded your system pip (probably through something like sudo pip install pip --upgrade)
pip x.x adjusts where its internals are situated. The pip3 command you're seeing is one provided by your package maintainer and is not a file managed by pip.
You can read more about this on pip's issue tracker
You'll probably want to not upgrade your system pip and instead use a virtualenv.
To recover the pip3 binary you'll need to sudo python3 -m pip uninstall pip && sudo apt install python3-pip --reinstall.
It should work fine if you use the first approach python3 -m pip ... instead of pip3 ....
Trying to install eyed3 but it's giving me this error:

ImportError: failed to find libmagic. Check your installation
Here's the pip install:
I tried to uninstall with pip and delete all the eyed3 files, then re-install and it still gave the same error. It also does the same thing with easy_install.
On Windows
You'll need DLLs for libmagic. #julian-r has uploaded a version of this project that includes binaries to pypi: https://pypi.python.org/pypi/python-magic-bin/0.4.14
pip install python-magic-bin==0.4.14
Works for me.
I fixed it by installing libmagic with this command
brew install libmagic
You need to install libmagic before you install eye3d.
Here is a link to the git.
https://github.com/ahupp/python-magic#dependencies
You can use this to install it:
pip install python-magic
I am trying to install a software using pip install and my python and pip versions are 3.5. but when I run sudo pip install -e . I get the following error.
Traceback (most recent call last):
File "/usr/local/bin/pip3.5", line 5, in <module>

Why Do I get an error with python 2.7 and please some one could sortout my issue.
Your pip version and python versions are separate. It looks like your package requires exactly pip 8.1.0. You have to either upgrade/downgrade to that version first, or modify the software to work with whichever pip you have available.
Also, it may be easier to install the software in a virtual environment rather than system/global one. Changing the system version of pip may break either current apps, or the future pip package updates.
I finally got pip install buildbot-slave to work on Win7 (thanks to another answer on this site), and now when I attempt to create a build slave via:
buildslave create-slave slavefolder blah.blah.com:9989 buildslave password
It kicks back the following error:
Traceback (most recent call last):
File "C:\Python27\Scripts\buildslave", line 3, in <module>
from buildslave.scripts import runner

raise ImportError(required + ": no module named zope.interface.")
ImportError: Twisted requires zope.interface 3.6.0 or later: no module named zope.interface.
I've got it all installed here is my pip freeze:
Twisted==14.0.0
argparse==1.2.1
buildbot-slave==0.8.9
stevedore==0.15
virtualenv==1.9.1
virtualenv-clone==0.2.5
virtualenvwrapper==4.3.1
virtualenvwrapper-win==1.1.5
zope.interface==4.1.1
Any recommendations would be greatly appreciated.
Try to uninstall zope.interface and reinstall the version 3.6.0 using the command
pip uninstall zope.interface
pip install zope.interface==3.6.0
Hope this helps.
After installing ipython on Windows via pip install ipython, I am unable to run it and receive the following error.

pyreadline was installed when ipython was via pip, but pip freeze shows warnings about the SVN location
> pip freeze

ipython==0.13.1
## FIXME: could not find svn URL in dependency_links for this package:

The solution was to uninstall the version of pyreadline pulled when ipython was installed (pip uninstall pyreadline) and download and install pyreadline-1.7.1.win32-py2.7.exe from http://www.lfd.uci.edu/~gohlke/pythonlibs/#pyreadline
