We’ll use the instance, options, when we create driver, the object that controls the Chrome beta app. These lines create an instance of the Options class, which we’re using to specify the directory where the Chrome beta app can be found.Here are some explanation that match the number comments in the code above: Option.binary_location='/Applications/Google Chrome Beta.app/Contents/MacOS/Google Chrome Beta'ĭriver = webdriver.Chrome(service=Service(ChromeDriverManager(version='1.20').install()), options=option) Here’s how I did it in Transmogrifier, my Python script that helps me assemble the Tampa Bay Tech Events list: from selenium import webdriverįrom import Optionsįrom import Serviceįrom webdriver_manager.chrome import ChromeDriverManager Once you’ve installed Chrome Beta, you just need to make your Selenium/ChromeDriver application or script use the appropriate version of ChromeDriver. This means that you can have the current release and the beta version installed on your machine at the same time.
The application has the name Google Chrome Beta and is considered a separate app from Google Chrome. As I’m writing this, the Google Chrome Beta site is hosting an installer for Chrome 104, or more accurately, Chrome 1.20. The challenge is that Chrome 104 is still in beta. This means that if you update to Chrome and ChromeDriver 104, your Selenium / ChromeDriver / Chrome setup will work again. Luckily, the bug has been fixed in ChromeDriver 104, which works specifically with Chrome 104.
If you regularly update Chrome or Chromium and use ChromeDriverManager to keep ChromeDriver’s version in sync with the browser, you’ve probably updated to ChromeDriver 1.53, which has a causes commands to ChromeDriver to sometimes fail. The culprit is ChromeDriver 103, and I wrote about it a couple of days ago in a post titled Why your Selenium / ChromeDriver / Chrome setup stopped working.ĬhromeDriver 103 - or more accurately, ChromeDriver 1.53 - works specifically with Chrome/Chromium 1.53. Instead, you’re probably seeing error messages that look like this: Message: unknown error: cannot determine loading statusįrom unknown error: unexpected command responseĠ chromedriver 0x000000010fb6f079 chromedriver + 4444281ġ chromedriver 0x000000010fafb403 chromedriver + 3970051Ģ chromedriver 0x000000010f796038 chromedriver + 409656
If you had an application or script that uses Selenium and ChromeDriver to control or automate instances of Chrome or Chromium, it’s probably not working right now.
