我创建了一个简单的flashkapp，我将在heroku上部署，第一次在heroku上部署python应用程序，据说我是枪手的新手。
Addtitional notes：使用虚拟环境。
烧瓶Flask的版本== 0.10.1
gunicorn == 19.3.0
使用＆＃39; python run.py＆＃39;的工作原理
使用＆＃39;领班开始＆＃39;我收到以下错误

从我读到的gunicorn允许创建多个线程，这使我认为线程正在尝试访问抛出已使用错误的相同端口。但是我不知道如何解决它，任何帮助表示赞赏。
答案 0 :(得分：8)
看起来你正在调用run：flaskapp而不是app：flaskapp而run.py正在尝试打开另一个实例。

首先，始终封装run：
if __name__ == '__main__':
flaskapp.run(debug=True)
并更新您的procfile以改为调用app.__init__.py：
web: gunicorn app:flaskapp --log-file=-
