Question

我有运行gunicorn和python程序的服务器。另一台服务器发送一个网址，有问题的服务器会抓取网址并发回一些信息。

我有selenium使用Xvfb在后台运行firefox选项卡。

这就是我现在重启服务器一段时间的原因：

sudo Xvfb :10 -ac
export DISPLAY=:10
sudo pkill gunicorn
gunicorn -b 0.0.0.0:8080 wsgi:app

突然之间，任何使用Xvfb的scrape都不再有效并且出错了，但是相同的代码仍可以在我的本地计算机上运行，因此我知道它与服务器上的Xvfb有关。

以下是停止工作后开始打印的新内容：

我已经尝试杀死所有Xvfb和Firefox作业并终止所有后台作业并重新启动，但仍然会出现同样的错误。

另外，最近的一个变化是当我输入：

sudo Xvfb :10 -ac

它已开始输出：

在删除一些错误阻止后，以下是新的错误代码：try：except：。

  ...
  File "./app/scraper/main.py", line 340, in uScrape
    driver = webdriver.Firefox()
  File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/firefox/webdriver.py", line 77, in __init__
    self.binary, timeout),

执行这3个命令后，此问题已修复

sudo apt-get upgrade firefox
pip install --upgrade selenium
sudo apt-get update

Xvfb刚开始失败而没有代码更改
