Installs chromedriver in a Heroku slug

heroku-buildpack-chromedriver

This buildpack installs chromedriver (the Selenium driver for Chrome) in a Heroku slug.

This buildpack only installs the chromedriver binary. To use Selenium with Chrome on Heroku, you'll also need Chrome. We suggest one of these buildpacks:

• heroku-buildpack-google-chrome to run Chrome with the --headless flag
• heroku-buildpack-xvfb-google-chrome to run Chrome against a virtual window server

Configuring the downloaded version of chromedriver.

By default, this buildpack will download the latest release, which is provided by Google.

You can control the specific version by setting the CHROMEDRIVER_VERSION variable to an explicit version e.g. 2.39.

I modified the compile script to check what the dowloaded google chrome version is, then download a correspond chromedriver. This should help me get over this error.

selenium.common.exceptions.SessionNotCreatedException: Message: session not created: This version of ChromeDriver only supports Chrome version 81
