根据Flask and uWSGI - unable to load app 0 (mountpoint='') (callable not found or import error)，我应该将from app import create_app更改为from app import create_app as application，从uwsgi.ini中删除callable = app，然后更改为application（）。run（...）。我尝试了一下，直到服务器能够启动，它才起作用。我在main.py中做了以下操作：
from app import create_app as application
if __name__ == '__main__':
application = application()
application.run('0.0.0.0', 5000, True)
现在，当尝试使用端点TypeError: create_app() takes 0 positional arguments but 2 were given
我不知道如何进行。有什么想法吗？
答案 0 :(得分：2)
使用
[uwsgi]
module = main
callable = app
uwsgi将导入main，从其中提取app，期望app是WSGI应用程序的实例。 Flask的一个实例是WSGI应用程序。在您使用的结构内执行此操作的标准方法是
from app import create_app
app = create_app()
使用uwsgi时，您发布的代码未调用create_app()，因为正在导入main.py。而且，当您实际调用create_app()时，需要从定义中删除未使用的arg1和arg自变量。
做
from app import create_app as application
令人困惑，特别是如果您曾经尝试过callable = application。
答案 1 :(得分：0)
您可以尝试将isMomentary = true更改为
uwsgi.ini
