How to add Chromedriver to PATH in linux?

The solution posted by @AnythingIsFine is indeed correct.

However in my case my pytest was still unable to find the chromedriver (despite it was correctly added to the PATH and from the terminal I could execute it).

So I've solved by adding an alias of the chromedriver in the /usr/bin directory:

sudo ln -s /path/to/chromedriver /usr/bin

Move Chromedriver to path with:

sudo mv -f ~/chromedriver /usr/local/bin/chromedriver

/usr/local/bin/chromedriver is path.

You can specify the absolute path to your chrome driver in your script as such:

from selenium import webdriver
driver = webdriver.Chrome(executable_path='/path/to/driver/chromedriver')

Or you can add the path to your webdriver in the PATH system variable as so:

export PATH=$PATH:/path/to/driver/chrome-driver

You may add the above line to your /home/<user>/.profile file to make it permanent.

Tested on Ubuntu 17.10 running Python 2.7.14

Hope this helps!
