Question

我使用Flask在virtualbox上建立了一个网站。该网站可以在localhost上打开，但我无法通过端口转发打开它，因此我将代码从manage.run()更改为manage.run(host='0.0.0.0')。

问题是我收到此错误：

typeerror run() got an unexpected keyword argument 'host'.

将manage.run()更改为manage.run(debug=True)时发生类似错误。我只是按照Flask文档。http://flask.pocoo.org/docs/quickstart/#a-minimal-application有谁能让我知道为什么我收到这个错误？

正如@ fangwz0577在评论中所说，他们使用App\Company.php解决了这个问题。其链接的归档版本为here。

接下来，创建manage.py文件。使用此文件加载其他内容未来的Flask脚本。 Flask-scripts提供了一个开发服务器和shell：
from flask.ext.script import Manager, Server
from tumblelog import app

manager = Manager(app)

 # Turn on debugger by default and reloader 
manager.add_command("runserver", Server(
    use_debugger = True,
    use_reloader = True,
    host = '0.0.0.0') )

Flask Error：typeerror run（）得到一个意外的关键字参数'host'
