Edge 浏览器驱动程序未在“Selenium”中启动

Question

I want to use Selenium to control the MS Edge browser.

However, I get an error and cannot move forward.

Please let me know the cause of this error and how to deal with it.

Answer 1

You need to send capabilities if you're using Mac OS. You can try to send an empty capability:

desired_cap={}

driver = webdriver.Edge(executable_path='/Users/yuchikawa/Dropbox/My Mac (YuのMacBook Pro)/Documents/scraping/msedgedriver', capabilities=desired_cap)

There're threads with same issues:
