Answer 1

`1. pip uninstall werkzeug -y # 卸载

1. pip install werkzeug==0.16.1 #安装0.16.1版本
2. 或者
3. python -m pip uninstall werkzeug -y # 卸载
4. python -m pip install werkzeug==0.16.1 #安装0.16.1版本`
5. 解决

Answer 2

找到问题了werkzeug的版本为1.0.0，这个版本中没有DispatcherMiddleware方法，所以降低版本可以正常启动了，不过我另一台deepin系统的机器的werkzenug也是1.0.0却能正常启动。。。
