Python pip install module is not found How to link python to pip location

Question

I m a newbie and I needed the pySerial and feedparser module for my projects  I m running Mountain lion   I followed the following tutorial so that I could upgrade to python 2 7 3 and then use the above mentioned modules   http   hackercodex com guide python-virtualenv-on-mac-osx-mountain-lion-10 8   I followed this tutorial till I installed pip  Instead of installing Virtualenv  I used the following commands to install pySerial and feedparser    pip install pySerial Requirement already satisfied  use --upgrade to upgrade   pySerial in  Library Python 2 7 site-packages Cleaning up      I assumed that this was already present and checked it  Python seems to be importing this just fine  My python version has been upgraded to 2 7 3 btw since I installed it using homebrew as mentioned in the tutorial   Then I tried installing feedparser    pip install feedparser Requirement already satisfied  use --upgrade to upgrade   feedparser in  usr local lib python2 7 site-packages Cleaning up      Notice how its in the site-packages directory in the usr local lib   All of my pip installs are being installed in that directory but python does not seem to be picking them up when i try importing them    How do I set the path so that python also looks there as well as core directory   Your help will be greatly appreciated   I tried looking for answers here  Pip installs but module is not found Why I can  39 t import beautifulsoup on mac using python 2 7 after installing it by using pip and or easy install   but niether of them are in the same situation as I am  I don t understand why this is happening as i edited my bash profile with the following    Set architecture flags export ARCHFLAGS  -arch x86 64    Ensure user-installed binaries take precedence export PATH  usr local share python  usr local bin  usr bin  bin  usr sbin  sbin   Load  bashrc if it exists test -f    bashrc  amp  amp  source    bashrc   then installed homebrew and then installed python 2 7 3 through homebrew  2 7 3 is now currently running on my machine    I figured all pip installs would be correctly linked

I also had this problem   I noticed that all of the subdirectories and files under  usr local lib python2 7 dist-packages  had no read or write permission for group and other  and they were owned by root   This means that only the root user could access them  and so any user that tried to run a Python script that used any of these modules got an import error     python Python 2 7 3  default  Apr 10 2013  06 20 15    GCC 4 6 3  on linux2 Type  help    copyright    credits  or  license  for more information   gt  gt  gt  import selenium Traceback  most recent call last     File   lt stdin gt    line 1  in  lt module gt  ImportError  No module named selenium  gt  gt  gt     I granted read permission on the files and search permission on the subdirectories for group and other like so     sudo chmod -R go rX  usr local lib python2 7 dist-packages   And that resolved the problem for me     python Python 2 7 3  default  Apr 10 2013  06 20 15    GCC 4 6 3  on linux2 Type  help    copyright    credits  or  license  for more information   gt  gt  gt  import selenium  gt  gt  gt     I installed these packages with pip  run as root with sudo    I am not sure why it installed them without granting read search permissions   This seems like a bug in pip to me  or possibly in the package configuration  but I am not very familiar with Python and its module packaging  so I don t know for sure   FWIW  all packages under dist-packages had this issue   Anyhow  hope that helps   Regards

For the sake of anyone also using visual studio from a windows environment   I realized that I could see my module installed when i ran pip install  py pip install  moduleName   py pip list   However debugging in visual studio was getting  module not found    Oddly  i was successfully running import  moduleName  when i ran the interpreter in powershell   Reason   visual studio was using the wrong interpreter at  C  Users  username  AppData Local Programs Python Python37     What I REALLY wanted was visual studio to use the virtualenv that i setup for my project   To do this  right click Python Environments in  solution explorer   select Add Virtual Environment      and then select the folder where you created your virtual environment   Then  under project settings  under the General tab  select your virtual environment in the dropdown     Now visual studio should be using the same interpreter and everything should play nice

how did you install easy install pip  make sure that you installed it for the upgraded version of python  what could have happened here is that the old  default  python install might be linked to your pip install  you might wanna try running the default version and importing the newly installed modules

Here is something I learnt after a long time of having issues with pip when I had several versions of Python installed  valid especially for OS X users which are probably using brew to install python blends    I assume that most python developers do have at the beginning of their scripts      bin env python   You may be surprised to find out that this is not necessarily the same python as the one you run from the command line  gt python  To be sure you install the package using the correct pip instance for your python interpreter you need to run something like    gt  bin env python -m pip install --upgrade mymodule

If your python and pip binaries are from different versions  modules installed using pip will not be available to python   Steps to resolve    Open up a fresh terminal with a default environment and locate the binaries for pip and python    readlink   which pip     Cellar python 2 2 7 15 1 bin pip  readlink   which python   usr local bin python3       lt -- another symlink  readlink  usr local bin python3    Cellar python 3 7 2 bin python3   Here you can see an obvious mismatch between the versions 2 7 15 1 and 3 7 2 in my case    Replace the pip symlink with the pip binary which matches your current version of python  Use your python version in the following command    ln -is  usr local Cellar python 3 7 2 bin pip3   which pip    The -i flag promts you to overwrite if the target exists   That should do the trick
