我正在从python3.5移至3.6。我已经创建了一个新的Virtualenv，并且正在尝试使用requients.txt文件安装所有软件包。但是，我遇到了一些问题 - 尤其是对于LXML。目前，我与之困惑的那个在下面。从最后一行的安装过程中，安装过程失速。
通过安装Python3.6-DEV来解决我遇到的以前的一些问题(LXML车轮未构建，红色代码块(。但是现在我有这个问题了。

由于我的python3.5.2 virtualenv在我的包裹似乎正常运行，因此它们应该在3.6上正常工作！
没关系！它只是花了很长时间才能做到这一点(没有任何详细的输出(。最终结束了。离开帖子，以防任何人面临同样的问题并开始急躁。
