Question

在MacOSX Sierra和XQuartz 2.7.11，Python 2.7下。我能够安装dryscrape及其所需的其他python包。我已经尝试了很多方法来使一些简单的代码工作，但我似乎无法让它工作。这是简单的代码：

#!/usr/bin/python
#coding: utf-8
import dryscrape
testurl = 'http://avi.im/stuff/js-or-no-js.html'
dryscrape.start_xvfb()
session = dryscrape.Session()
session.visit(testurl)
exit()

你可以看到它是一个简单的python脚本文件。它在start_svfb()或Session()行都失败了。我可以发布错误等，但是我可以开始讨论我应该设置，运行和测试哪些检查列表以确保X11环境是正确的吗？我是否在OS X终端或XQuartz下运行脚本？我错过了什么？等？

这是python的最后一个回溯：
