Edit: Problem solved.

我使用python和flask创建了一个基本应用程序。我已经将应用程序部署到heroku，heroku没有引发任何异常或错误。但当我打开我的应用程序时，我会收到一条消息“应用程序错误”。 该应用程序在我的本地主机和pythonanywhere.com上运行良好

我也在网上和stackoverflow上寻找一些解决方案。没有找到任何解决问题的方法

Procfile

web:gunicorn yesillcs:app

yesillcs.py

from flask import Flask, render_template

app = Flask(__name__)

@app.route("/")
def page_index():
    return render_template('index.html')

@app.route("/notifications")
def page_notifications():
    return render_template('notifications.html')

@app.route("/login")
def page_login():
    return render_template('login.html')

@app.route("/logs")
def page_logs():
    return render_template('logs.html')

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

Heroku正在动态分配Gunicorn应在其上为您的应用程序提供服务的端口。您没有告诉Gunicorn连接此端口。更新Procfile，使其看起来像这样

Procfile

web: gunicorn  bind 0.0.0.0:$PORT yesillcs:app

您的Procfile应该更改为重复“module:app name”格式，因此指向您的python文件/模块。在这里：

web:gunicorn yesillcs:app

（您的Procfile现在是web:gunicorn deploy:app，因此heroku正在deploy.py中查找app-这在您的repo中不存在）
