“导入错误：没有模块名为”，在Heroku

我在烧瓶应用程序正在与结构的基础上http://code.tutsplus.com/tutorials/an-introduction-to-pythons-flask-framework--net-28822截图烧瓶中。为了在本地工作，我一直在运行routes.py文件。

我现在正试图在heroku上部署使用gunicorn后跟https://www.udacity.com/wiki/ud330/deploy。继方向，我requirements.txt包含：

$ pip Freeze 
Flask==0.10.1 
Flask-Mail==0.9.1 
Flask-SQLAlchemy==2.1 
Flask-WTF==0.12 
Jinja2==2.8 
MarkupSafe==0.23 
SQLAlchemy==1.0.11 
WTForms==2.1 
Werkzeug==0.11.3 
blinker==1.4 
gunicorn==19.4.5 
itsdangerous==0.24

我不知道该怎么把我的Procfile，我试过几个变化，包括：

但我得到按照Heroku的日志：

而且我runserver.py文件包含：

from intro_to_flask import app 

app.run(debug=True)

我该如何解决这个问题？

编辑改变Procfile到：

web: gunicorn runserver:app

你需要指向的东西是app对象，如您展示的是runserver文件中。所以：

gunicorn runserver:app

感谢您期待丹尼尔，请参阅编辑.. – user61629

你有一个奇怪的文件在该模块中的名称：它应该只是'__init __。py'，没有'a'。 –

嗨丹尼尔，我解决了，但它仍然没有工作。请参阅编辑2. – user61629

如果从烧瓶文件intro_to_flask和你的实例变量的名称创建应用程序实例的应用程序：

intro_to_flask.py

... 
app = Flask() 
...

更改Procfile这个

web: gunicorn intro_to_flask:app
