If we run the script again, it should work fine and a browser window should open. It’s at your discretion what version you choose, as long as it meets the requirement above. At the time of writing this, I had to revert to version 71 of chrome. To solve this issue, we’ll uninstall the version of chrome that we are currently using and downgrade to a version that satisfies the criteria above. This error is triggered when the version of chrome downloaded is incompatible with the chrome driver we are using. Once we’ve done this we can run the script again and surprise, surprise we get another error! This time the message is (at the time of writing): Chrome version must be between 70 and 73 We can tackle this by downloading the Chrome browser. This error is brought about when we do not have the chrome browser installed. Running the script, to our surprise, gives us an error with the message: unknown error: cannot find chrome binary Let’s save this and move over to the terminal. Here is a basic script to get up and running with selenium: from selenium import webdriver # Initialize the driver driver = webdriver.Chrome() # Open provided link in a browser window using the driver driver.get('') We can now go ahead and create a python script that utilizes it. When the installation is done, we can check the version of chrome driver by running the following command on the terminal: chromedriver -versionĪt the time of writing, the latest version of chromedriver installed by homebrew is version. We do this by executing the following command on the terminal: brew cask install chromedriver Once we’ve installed selenium, it’s time to install the chromedriver using homebrew. We can do this by running the following command on the terminal: pip install selenium You can learn more about homebrew and how to install it here. Homebrew is a package manager that installs packages in their own directory and then symlinks them in “usr/local”.

Code documentation on selenium-python can be found here. I won’t go into too much detail about selenium in this post in order to keep it short. I doubt you need much of an introduction to python, selenium is a framework that facilitates browser automation. In my first project, my chosen tools were python, selenium, and homebrew. I’ve been working on some web crawling projects recently.
