運行pyspider常見的錯誤：
①ValueError: Invalid configuration: - Deprecated option ‘domaincontroller’: use ‘http_authenticator.domain_controller’ instead.
②ImportError: cannot import name ‘DispatcherMiddleware’
這里我就不寫了，網上一搜還挺多的，就這個問題我在網上找了好長時間也沒有找到解決方案。為了大家在遇到相同問題時能夠少花點時間，我這里就把我的解決思路分享給大家參考。

這是我運行pyspider命令時出現的錯誤(我在解決上面提的兩個錯誤后出現這個錯誤)：

遇到這個情況你可以看下你在成功執行pip install werkzeug==0.16.0語句時，有沒有出現下面情況

這個是你flask版本的問題，你只要降低下flask版本就行了

pip uninstall flask #卸載 你也可以省略這步，直接pip install flask==1.0 pip install flask==1.0 #我這里改成1.0就行了，改成其他低版本應該也沒問題，有興趣自己試下

修改flask版本后：

總結
