执行时，报出问题：SyntaxError: invalid syntax
第一步：改变量名
- async从 python3.7 开始已经加入保留关键字中，所以async不能作为函数的参数名.
- 修改/Library/anaconda3/lib/python3.7/site-packages/pyspider路径下的python文件中的async为async_mode（其他名也可以）替换好的代码在下方。
-
- 1.run.py （直接全部替换，async为async_mode）

第二步：修改webdav.py第209行
如果报错，ValueError: Invalid configuration: - Deprecated option 'domaincontroller': use 'http_authenticator
- 原因是因为WsgiDAV发布了版本 pre-release 3.x。
- 解决办法
- 在安装包中找到pyspider的资源包，然后找到webui文件里面的webdav.py文件打开，修改第209行即可。
把
'domaincontroller': NeedAuthController(app),
修改为：
'http_authenticator':{ 'HTTPAuthenticator':NeedAuthController(app), },
第三步：降低WsgiDAV版本
python -m pip install wsgidav==2.4.1
然后再执行pyspider all就能够通过http://localhost:5000打开页面了。
