Answer 1

将firefox更新为＆gt; = 48以运行selenium3

https://ftp.mozilla.org/pub/firefox/releases/49.0.2/win64/en-GB/Firefox%20Setup%2049.0.2.exe

Answer 2

发现问题可能是一个错误在geckodriver.log中，我注意到firefox.exe的调用方式有些奇怪

1478478477543 geckodriver :: marionette INFO启动浏览器C：\ Program 文件（x86）\ Mozilla Firefoxirefox.exe

当我将firefox路径从firefox.exe更改为大写F Firefox.exe时。每个人都在工作

binary = FirefoxBinary('C:\Program Files (x86)\Mozilla Firefox\Firefox.exe')

通过geckodriver的Selenium Firefox webdriver导致错误：无法启动浏览器：找不到实体
