The benefit of running this in the notebook is that you don't need to know the exact path to pip running in the same virtual environment as Jupyter, so I use this trick a lot.Downloads and installs the chromedriver binary version 1.24 for automated testing of webapps.

Since I was planning to use it from a Jupyter Notebook I actually installed it by running the following in a cell in a notebook: %pip install selenium I installed Selenium using pip for Python 3: pip install selenium Clicking that worked around the signing issue. To fix this, go to System Preferences -> Security & Privacy - there was a prompt there about the binary, with an "open this anyway" button. # A window displayed on macOS with an error The first time I ran it I got an error complaining that the binary has not been signed: ~/bin/chromedriver I decided to put this in my ~/bin directory. Unzipping this gave me a chromedriver binary file. I have Chrome 85 so I downloaded the chromedriver_mac64.zip file from Message: session not created: This version of ChromeDriver only supports Chrome version 85 Without using homebrewĬhromeDriver is available from the official website here: Knowing how to upgrade an existing version is useful if you are seeing an error like this one: To upgrade an existing installation do this: brew upgrade chromedriver -cask You still need to run it once in the terminal chromedriver to get the macOS error, then allow it in the Security & Privacy preferences - see below. This also ensures chromedriver is on your path, which means you don't need to use an explicit chromedriver_path later on. This is by far the easiest option: brew install chromedriver -cask
