How to fix No module named ‘selenium’ error in Python 3.

This error pops up in Python3 even after installing selenium module using pip3.

You might have seen No module named 'selenium' error while importing selenium module in Python 3 even though you have already installed the module using pip3 install selenium command.

root@shashank-mbp /U/s/D/Employee-App# python3 integration-test.py
Traceback (most recent call last):
  File "integration-test.py", line 6, in <module>
    from selenium import webdriver
ModuleNotFoundError: No module named 'selenium'

And pip says it has already installed the selenium module.

root@shashank-mbp /U/shashanksrivastava# pip3 install selenium
Requirement already satisfied: selenium in /Library/Python/3.7/site-packages (3.141.0)
Requirement already satisfied: urllib3 in /Library/Python/3.7/site-packages (from selenium) (1.25.6)

And the funny thing is that it works without any issues in Python 2.

So, how do we fix this problem?

After scratching my head for several hours, I finally found that this module had to be installed manually instead of using pip3.

To install the selenium module, simply…

• Download the package from selenium-3.141.0.tar.gz
• Unpack it.

root@shashank-mbp /U/s/Downloads# tar xf selenium-3.141.0.tar.gz root@shashank-mbp /U/s/Downloads# cd selenium-3.141.0/ root@shashank-mbp /U/s/D/selenium-3.141.0# ls 
CHANGES LICENSE MANIFEST.in PKG-INFO

• Now, install the module by executing python3 setup.py install command.

root@shashank-mbp /U/s/D/selenium-3.141.0# python3 setup.py install running install running bdist_egg…

Now you can import the module in Python 3.
