Python/Selenium Firefox驱动程序在Ubuntu上失败，在Windows上正常

Question

我在Ubuntu（Amazon EC2 t2.small）上安装了以下软件：geckodriver:0.24.0firefox:68.0.1selenium:3.141.0

在Windows上，我有：geckodriver:0.24.0，firefox:67.0.4，selenium:3.141.0

我不知道不同的火狐版本是否是问题所在，但是我在Ubuntu上下载67.0.4时遇到了问题（以下）。我将提取的火狐文件夹 /usr/bin/firefox但是当我运行火狐-v时，它给我命令“火狐”找不到，但这是另一个问题。

我正在运行以下代码块：

share_url =  ( driver.current_url )

...code here...

# scroll down a couple times
for _ in range(4):
    driver.execute_script("window.scrollTo(0, document.body.scrollHeight);")
    time.sleep(1)

不同版本的逻辑完全相同。它也在早些时候起作用。

这在Ubuntu上失败，并出现以下错误，在Windows上运行良好。

我的经验是，Selenium对它运行的浏览器版本非常敏感。我一定会努力解决你安装67.0.4时遇到的任何问题，因为我很确定这会让你再次上路。
