python - ImportError: No module named 'selenium'

Question

I'm trying to write a script to check a website. It's the first time I'm using selenium. I'm trying to run the script on a OSX system. Although I checked in /Library/Python/2.7/site-packages and selenium-2.46.0-py2.7.egg is present, when I run the script it keeps telling me that there is no selenium module to import.

This is the log that I get when I run my code:

Traceback (most recent call last):
  File "/Users/GiulioColleluori/Desktop/Class_Checker.py", line 10, in <module>
    from selenium import webdriver
ImportError: No module named 'selenium'

Answer 1

If you have pip installed you can install selenium like so.

pip install selenium

or depending on your permissions:

sudo pip install selenium

For python3:

sudo pip3 install selenium

As you can see from this question pip vs easy_install pip is a more reliable package installer as it was built to improve easy_install.

I would also suggest that when creating new projects you do so in virtual environments, even a simple selenium project. You can read more about virtual environments here. In fact pip is included out of the box with virtualenv!
