无法连接到FlaskEve API

Question

我想用Eve来操纵MongoDB上的数据。 我按照夏娃的官方指示去测试结果，结果失败了

Eve's official instruction for quick-start

触摸同一文档中的两个文件，如下所示

#/run.py

from eve import Eve
app = Eve()

if __name__ == '__main__':
    app.run()

#/settings.py

DOMAIN = {'people': {}}

结果

之后我键入$ python run.py在命令行中启动API，结果什么也没发生。 它应该按照官方指示告诉我地址

#It should be like this
$ python run.py
 * Running on http://127.0.0.1:5000/

$ curl -i http://127.0.0.1:5000
HTTP/1.0 200 OK
Content-Type: application/json
Content-Length: 82
Server: Eve/0.0.5-dev Werkzeug/0.8.3 Python/2.7.3
Date: Wed, 27 Mar 2013 16:06:44 GMT



#My situation
$ python run.py
 * nothing

$ curl -i http://127.0.0.1:5000
curl: (7) Failed to connect to 127.0.0.1 port 5000: Connection refused

我真的不知道该怎么处理
