[英]“module object not callable” with Waitress
I am trying to deploy my app on Heroku.我正在尝试在 Heroku 上部署我的应用程序。 I have to use Windows, and gunicorn won't work.我必须使用 Windows,而 gunicorn 不起作用。 I tried waitress, which keeps giving me a "module not callable" error whenever I try to load any page.我试过女服务员,每当我尝试加载任何页面时,它都会给我一个“模块不可调用”的错误。
Note: I haven't deployed it on web so far, was trying heroku local
before creating a publicly accessible one.注意:到目前为止,我还没有在网络上部署它,在创建一个可公开访问的heroku local
之前尝试了它。 It works on localhost
when using PyCharm.使用 PyCharm 时,它适用于localhost
。

Any idea how to solve this?知道如何解决这个问题吗?
In your Procfile
, try changing在您的Procfile
,尝试更改
web: waitress-serve --port=5000 myapp:application
to到
web: waitress-serve --port=5000 myapp:app
The last argument to waitress-serve
is MODULE:OBJECT
, where OBJECT
is the application object in MODULE
. waitress-serve
的最后一个参数是MODULE:OBJECT
,其中OBJECT
是MODULE
的应用程序对象。 Here, you've named your application app
:在这里,您已将应用app
命名为app
:
app = create_app()
(You're not showing us all of your code, but it looks like myapp.application
is in fact a module, not an object. You import create_app
, db
, and login_manager
from it in your sample code.) (您没有向我们展示您的所有代码,但看起来myapp.application
实际上是一个模块,而不是一个对象。您在示例代码中从中导入create_app
、 db
和login_manager
。)
Waitress has it's own app
, so you need to distinguish your app
correctly. Waitress 有自己的app
,因此您需要正确区分您的app
。 @Chris's answer shows you how to do so via Procfile
. Procfile
的回答向您展示了如何通过Procfile
做到这Procfile
。 Here's another way, for those using Flask:对于那些使用 Flask 的人来说,这是另一种方式:
app/ init .py :应用程序/初始化.py :
from flask import Flask
app = Flask(__name__, template_folder="some path", static_folder="another path")
main.py主文件
from waitress import serve
from app import app as my_app # renamed to distinguish from waitress' 'app'
if __name__ == "__main__":
serve(my_app, host="localhost", port=5005)
This allows you to keep your app named app
in a routes file, since that is isolated from waitress这允许您将名为app
在路由文件中,因为它与女服务员隔离
app/routes.py :应用程序/routes.py :
@app.route('/dothing1', methods=['POST', 'GET'])
def dothing1():
pass
