我正在尝试在Ubuntu Droplet上运行Flask应用程序但是当我尝试使用python app.py运行应用程序时,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)

    run_simple(host, port, self, **options)

    reloader.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安装软件包,因为我很确定这是一个特定于Windows的模块。有什么方法可以解决这个问题吗?

我遇到了同样的问题。据我所知,这是因为最后一个更改重新加载器的Werkzeug版本发生了一些变化。

安装watchdog可以解决我的问题:

pip install watchdog

现在,我没有看到“*使用stat重启”,而是看到“*使用inotify重新加载器重新启动”,而且一切正常。
