Python-导入paypalrestsdk导致ImportError：没有名为_winreg的模块

Question

Any time I try to import paypalrestsdk in a python file, I get

Traceback (most recent call last):
  File "runserver.py", line 3, in <module>
    app.run(debug=True)
  File "/usr/local/lib/python2.7/dist-packages/flask/app.py", line 772, in run

  File "/usr/lib/python2.7/dist-packages/six.py", line 76, in _import_module
    __import__(name)
ImportError: No module named _winreg

I'm using Flask and the import was in the routes.py, but I got the same error when I put the import in the init .py

Install the module watchdog or downgrade the werkzeug's version. There seems to be some issues with the latest werzeug's version as explained here AWS ec2 winreg not found
