Tonight I am trying to get the package called "requests" installed and have begun fumbling around with the terminal and do not have very much intuition when it comes to this sort of thing.
Computer is a mac mini, osx version 10.9.4
In /Library/Python I have 4 folders: 2.3 2.5 2.6 and 2.7.
In /Applications I have "Python 2.7" and "Python 3.4"
I can open IDLE and type 8+8 and I get 16 just fine.
Here is the error I am getting in terminal:
host-210-117:~ Mario$ python
ImportError: No module named site
host-210-117:~ Mario$ pip
ImportError: No module named site
My goal is to run this command in the terminal:
pip install requests
I believe pip is already installed. I run the file "get-pip.py" in IDLE and this is what it says:
Requirement already up-to-date: pip in /Library/Python/2.7/site-packages/pip-1.5.6-py2.7.egg Cleaning up...
This may have something to do with paths? I would appreciate some guidance/hints/tips, thanks!
Oh and just a little more info that might help solve this question. Here is the first few lines of the program I'm running:
import base64
import hmac
import json
import requests
import time
import urllib
import os
Which gives me this error in IDLE (so I guess it importing those first few packages with no problem?) :
>>>

From what I can tell you have three versions of Python on your system.
- The one that comes with OSX
/Library/Frameworks/Python.framework/Versions/2.7/ - Python 2.7 from python.org
/Library/Python/2.7/site-packages - Python 3.4 from python.org
pip is installed against the Python 2.7 version you downloaded (the one you see in your Applications folder), unfortunately the default Python for your shell is the one that's bundled with OSX, and there is no pip installed there.
IDLE is also bundled with the Python that you downloaded, which is why it keeps telling you that pip is installed, but it doesn't work from the shell.
Since you are probably using the Python downloaded from python.org as your "primary" Python (after all, its the one with IDLE that you are using), you need to set your shell environment to point to this Python as default.
The easiest way to do that is to add a variable in .bashrc that creates an alias python and points it to the right binary. To do that, add this line to /Users/yourusername/.bashrc - files with . are hidden by default, so you'll have to write the entire file name in the command line to open it. Add the following line:
alias python=/Library/Python/2.7/python
Save the file and then close all terminal windows and open it again. Now type pip and it should work correctly, and then you can proceed to installing requests.
For future reference, try to stick with one version of Python. I personally ignore the bundled version and use the one from brew, but you can stick to the Python downloaded from python.org.
I fixed mine with:
brew reinstall python
It fixed all my broken paths. I think I broke it with a broken brew package that had a wrong python version dependancy or something like that.
site.py is a standard module that is run by python by default. It allows tweaking sys.path and running some code before your code starts running. It should live in the standard library and can hardly be somehow absent. However, you can disable automatic importing of the module by passing -S switch to python.
Anyway, you should somehow inspect why the module can not be imported. Try to examine sys.path list.
You are trying to install the package in '/Library/Python/2.7/site-packages/requests' but it requires root permissions to do so. This should do the trick:
$ sudo pip install requests
I met the same question, and error info is:
ModuleNotFoundError: No module named 'xxx'
and finally solved by
brew install python3
brew link python3
sudo python3 -m pip install xxx
// or `sudo python3 -m pip install -r requirements.txt`
