突然接到一个项目是关于pyspider，遇到了一些小坑，百度一下发现并没有很好的解决所以研究了一下。
我所使用的python版本是3.6.8，因为pyspider是对pip有版本要求的，所以自动升级一下。
升级pip
•# pip install –upgrade pip
一切配置好之后，就在CMD中运行 pyspider all 来看能否跑起来。
这是成功的样子，说明可以了。
不过路上谁能不遇坑，人家各种成功，到了我这里就是各种错误，我就把这些错误整合一下。
首先第一个错误：python3.7不兼容pyspider问题(出现占用关键字的问题)
Python 3.5中引入了async和await，它们在Python 3.7中成为关键字。
所以需要替换一下关键字。
第二个问题也就是我遇到的问题：[root@localhost python]# pyspider all

这是我遇到的，然后网上居然没有特别明显的解决，费劲千辛万苦才查到，这是WsgiDAV发布了版本 pre-release 3.x导致的，所以只要把版本降下来就好了。
将wsgidav替换为2.4.1
•# python -m pip install wsgidav==2.4.1
然后运行 pyspider all 发现居然可以了。上一张成功的图片。
然后很欢快的打开浏览器输入：localhost：5000
