我正在尝试在 Ubuntu Droplet 上运行 Flask 应用程序,但是当我尝试运行该应用程序时,python app.py我得到以下回溯:

* Running on http://0.0.0.0:4000/ (Press CTRL+C to quit)
 * Restarting with stat
Traceback (most recent call last):
  File "app.py", line 49, in <module>
    app.run('0.0.0.0', port=4000, debug=True)
  File "/usr/local/lib/python2.7/dist-packages/flask/app.py", line 772, in run
    run_simple(host, port, self, **options)
  File "/usr/local/lib/python2.7/dist-packages/werkzeug/serving.py", line 622, in run_simple
    reloader_type)
  File "/usr/local/lib/python2.7/dist-packages/werkzeug/_reloader.py", line 269, in run_with_reloader
    reloader.run()
  File "/usr/local/lib/python2.7/dist-packages/werkzeug/_reloader.py", line 159, in run
    for filename in chain(_iter_module_files(), self.extra_files):
  File "/usr/local/lib/python2.7/dist-packages/werkzeug/_reloader.py", line 70, in _iter_module_files
    for package_path in getattr(module, '__path__', ()):
  File "/usr/lib/python2.7/dist-packages/six.py", line 116, in __getattr__
    _module = self._resolve()
  File "/usr/lib/python2.7/dist-packages/six.py", line 105, in _resolve
    return _import_module(self.mod)
  File "/usr/lib/python2.7/dist-packages/six.py", line 76, in _import_module
    __import__(name)
ImportError: No module named _winreg

我无法使用 pip 或 apt-get 安装该软件包,因为我很确定这是一个特定于 Windows 的模块。有什么办法可以解决这个问题吗?

我遇到了同样的问题。据我了解,这是因为最后一个 Werkzeug 版本中的一些更改会更改重新加载器。

安装看门狗可以解决我的问题:

pip install watchdog

现在,我看到的不是“* Restart with stat”,而是“* Restart with inotify reloader”,一切正常。
