Edge 浏览器驱动程序未在 "Selenium" 中启动

Question

我想用Selenium来控制MS Edge浏览器。

但是，我得到一个错误，无法继续。

请告诉我这个错误的原因和处理方法。

#环境信息

OS: MacOS Big Sur / Ver. 11.2.3 (M1)
计算机语言：Python3.6
目标浏览器:Microsoft Edge / Ver.89.0.774.75
已安装 webdriver:我已经为“目标”安装了合适的浏览器”。(URL:https://developer.microsoft.com/ja-jp/microsoft-edge/tools/webdriver/)

#代码

*注释掉的“Chrome”将正常启动。


from selenium import webdriver

#driver = webdriver.Chrome(executable_path='/Users/yuchikawa/Dropbox/My Mac (YuのMacBook Pro)/Documents/scraping/chromedriver')
driver = webdriver.Edge(executable_path='/Users/yuchikawa/Dropbox/My Mac (YuのMacBook Pro)/Documents/scraping/msedgedriver')

如果您使用 Mac OS，则需要发送功能。您可以尝试发送一个空的能力：

desired_cap={}

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