我用 Flask 在 virtualbox 上建立了一个网站。该网站可以在本地主机上打开，但我无法通过端口转发打开它，所以我将代码从 更改manage.run()为manage.run(host='0.0.0.0').
问题是我收到此错误：
typeerror run() got an unexpected keyword argument 'host'.
manage.run()更改为时会发生类似的错误manage.run(debug=True)。我只是遵循了 Flask 文档。http://flask.pocoo.org/docs/quickstart/#a-minimal-application谁能告诉我为什么我会收到这个错误？
