Python Question

Modules are installed using pip on OSX but not found when importing

I successfully install different modules using pip and they are shown in the

pip list

such as:

beautifulsoup4 (4.4.1)
requests (2.10.0)
Scrapy (1.1.0)

From Terminal

However, whenever I try to import it

import beautifulsoup4
import bs4
import Scrapy
import requests

the following error is shown:

$ python
Python 2.7.5 (default, Mar 9 2014, 22:15:05)
[GCC 4.2.1 Compatible Apple LLVM 5.0 (clang-500.0.68)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import requests
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named requests

Update: if I launch python when I am at the correct site-packages directory

$ pwd
$ python
Python 2.7.5 (default, Mar 9 2014, 22:15:05)
>>> import requests
>>> import bs4
>>> import scrapy

Then it works. This would solve the issue if writing directly on the Terminal. However, I have no clue about how to make it work inside a file.py, which will be the normal use.

As far as I know, I only have Python2.7 installed.

From file.py

If I have a file.py saved in some local folder. This contains, for instance

import requests
from bs4 import BeautifulSoup

when I try

python file.py

I get the same error.


Same happens with any other module from the list.
I would think pip is installing them in a directory that Python is not reading, but as per what I read, it is the correct one.

They are all installed here:


Output requested by Padraic Cunningham:

$ which -a pip
$ which -a python

Output requested by leovp:

$ pip -V
pip 8.1.2 from /usr/local/lib/python2.7/site-packages (python 2.7)

Threads already checked

I have checked the following threads, but unfortunately they did not help me to solve the issue:

Any ideas of what the problem is?

Since your problem maybe caused due to various reason, I have listed down a few of them here :

The link you were looking for : https://pythonhosted.org/setuptools/setuptools.html#development-mode

  • It may also happen if you have two versions of python installed. If the pip that you are accessing is of one version & the python interpreter used is another.

So just see to that you are using the same version of python to install and use the package.

You may fix this using alias,

First, set up a shell alias:

alias python=/usr/local/bin/python3

Then, type that at a prompt, or put it in your ~/.bashrc so that whenever you open python from the terminal the correct version opens.

  • If both of the above methods don't work for you then check this :

ImportError No module named or this
