ModuleNotFoundError: No module named 'werkzeug.wsgi.middleware'; 'werkzeug.wsgi' is not a package

[connesy]

When using from werkzeug.wsgi import DispatcherMiddleware I get a DeprecationWarning:

DeprecationWarning: The import 'werkzeug.wsgi.DispatcherMiddleware' is deprecated and will be removed in Werkzeug 1.0. Use 'from werkzeug.wsgi.middleware.dispatcher import DispatcherMiddleware' instead.
  from werkzeug.wsgi import DispatcherMiddleware

But when I use that instead, I get a ModuleNotFoundError:

Traceback (most recent call last):
  File "services/server.py", line 8, in <module>
    from werkzeug.wsgi.middleware.dispatcher import DispatcherMiddleware
ModuleNotFoundError: No module named 'werkzeug.wsgi.middleware'; 'werkzeug.wsgi' is not a package

Werkzeug version 0.16.0.

It seems to work when I use

from werkzeug.middleware.dispatcher import DispatcherMiddleware

without the .wsgi., without a DeprecationWarning.

@davidism I try to make a pr for fix this issue, incorrect warning maybe puzzled

The current documentation (found here) suggests that the proper import is from werkzeug.middleware.dispatcher import DispatcherMiddleware, but this does not work either. The only form that works is from werkzeug import DispatcherMiddleware:

>>> from werkzeug.wsgi.middleware.dispatcher import DispatcherMiddleware
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'werkzeug.wsgi.middleware'; 'werkzeug.wsgi' is not a package
>>> from werkzeug.middleware.dispatcher import DispatcherMiddleware
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
