烧瓶应用程序工厂找不到应用程序错误

Question

我正在尝试创建Flask应用，但出现错误

public class Test {

    public static void main(String[] args) {

        int multiplier = 1;
        for (int index = 1; index < 11; index++) {
            //System.out.printf("%2d * %2d = %2d%10s%2d * %2d = %2d%n", index, multiplier, (multiplier * index), "", index, multiplier + 1, ((multiplier + 1) * index));
            System.out.printf("%2d * %2d = %2d", index, multiplier, (multiplier * index));
            System.out.printf("%10s%2d * %2d = %2d%n", "", index, multiplier + 1, ((multiplier + 1) * index));
        }

    }
}

unable to find application callable in file __init__.py unable to load app 0 mountpoint='' callable not found or import error appfactory __init__.py 文件是

。

__init__.py

如果我删除了 from flask import Flask def create_app(): app = Flask(__name__) @app.route('/hello') def hello(): return 'Hello' return app ，它将起作用。 但是我不确定如何在应用程序工厂中使它正常工作。 我什至将def create_app()放在了create_app()文件的末尾，并且遇到了同样的错误
