我尝试在AWS机器上通过Python中的selenium调用firefox。
我查看之前的帖子（this one和this one）。 但是，他们的解决方案并不直接适用于我。 我使用了以下代码示例，但是出现了如下所述的错误。
from pyvirtualdisplay import Display
from selenium import webdriver
display = Display(visible=0, size=(1024, 768))
display.start()
driver= webdriver.Firefox()
driver.get("http://www.somewebsite.com/")
<---some code--->
#driver.close() # Close the current window.
driver.quit() # Quit the driver and close every associated window.
display.stop()
我收到以下错误：
> driver= webdriver.Firefox()
Traceback (most recent call last):

raise WebDriverException("The browser appears to have exited "
selenium.common.exceptions.WebDriverException: Message: The browser appears to have exited before we could connect.
If you specified a log_file in the FirefoxBinary constructor, check it for details.
我安装了xvfb和pyvirtualdisplay而没有错误。 我的firefox是最新的。
如果我单独运行firefox，我也会遇到如下错误。
