'No module named requests' even if I installed requests with pip
Question:
I’m trying to test if requests module has been well installed. But I’m getting the following error :
raceback (most recent call last):
File "/Users/macbookpro/Desktop/test.py", line 1, in <module>
import requests
ImportError: No module named requests
when trying to run the following test script:
import requests
print 'test'
But I have installed requests with pip, and pip list command gives the following result :
MBPdeMacBook2:~ macbookpro$ pip list
arrow (0.7.0)
beautifulsoup4 (4.4.1)
classifier (1.6.5)
coursera-dl (0.6.1)
Django (1.8.6)
html5lib (1.0b8)
keyring (9.0)
lxml (3.6.0)
Pillow (3.4.2)
pip (8.0.2)
pyasn1 (0.1.9)
requests (2.14.2)
setuptools (19.4)
six (1.10.0)
urllib3 (1.16)
vboxapi (1.0)
virtualenv (13.1.2)
wheel (0.26.0)
Why requests isn’t being imported ?
EDIT :

Answers:
I am not 100% sure, but the paths from which python and which pip may indicate that you have two versions installed. The Python version being the old one that was shipped with OS X, and another version.
I would advice you to install Python27 (or even better Python3) from brew.
You can install brew with a single command, and another one for installing Python27/3. When this is done you set the PATH variable in your shell rc file and you should be good to go.
I have Python27 installed (via brew) and my (working environment) reports the following paths:
which python: /usr/local/bin/python
which pip: /usr/local/bin/pip
And
python --version: 2.7.15
pip --version: pip 9.0.1 from /usr/local/lib/python2.7/site-packages (python2.7)
In general, you should get into the habit of working in a virtualenv. I find the documentation here to be helpful.
If you install all of your dependencies within the virtual environment, you’ll be (mostly) sure that you are installing those deps. in the same environment that you’re running the jobs in.
For your case, on the command line go to the directory where your code lives and run
pip install virtualenv
virtualenv my_project
source my_project/bin/activate
Now that the virtualenv is active you can
pip install requests
Only what is installed in the virtualenv will be available. This will keep your system clean. Each project should get its own virtualenv, meaning only the dependencies needed for each project will be available to them. This way you could, say, have version 1 of some dependency installed for one project and version 2 for another. They won’t come into conflict.
After you have installed all the dependencies, run
pip freeze > requirements.txt
To get a list of all the dependencies for the project saved. Next time you need to install these, you simply run
pip install -r requirements.txt
Once you are done working in the virtualenv, run
deactivate
This can occur for example if pip is actually pip3 and python is actually python2.7.
In your case the which pip and which python eliminate this possibility but it just happened to me.
The solution was to do pip2 instead of pip; if the situation was reversed you can use pip3.
I experienced this same issue on Ubuntu 18.04 LTS, to check that, I first checked if requests library was installed on my system or not.
Run these commands on your terminal inside the virtual environment in which you working
$ python
Then the python command line opens, then run
>>> import requests
After this if you get an ImportError saying, No module named requests, then it means the dependency has not been installed properly. If there is no such error, then it means the dependency is installed successfully.
Simply go inside your virtual environment and run below commands:
1). pip install –user pipenv
2). pipenv install requests
after executing the above commands cd to your app folder inside the virtual environment and just run it. Hopefully now it will run.

There is a possibility that you are having more than one Python installations and you have this module installed in one installation but using another for execution.
You can check the Python interpreter you are using for execution.
Run
pip show <module name>
and check the module causing issue, is in which location, this will tell you which Python installation you should use as your interpreter or else you can copy the module files manually to your current Python interpreter installation’s location.
