    from werkzeug.wsgi import DispatcherMiddleware
ImportError: cannot import name 'DispatcherMiddleware'

哪位大神给解答一下，谢谢。。

回答：

`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

回答：

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。。。

以上是 pyspider报cannot import name &#x27;DispatcherMiddleware&#x27;求解 的全部内容， 来源链接： utcz.com/a/160534.html
