OSError：[Errno 98]地址已在使用中-Heroku

Question

我正在尝试将项目https://github.com/kc1/flask-huey-example部署到heroku，以允许使用任务队列和烧瓶。项目布局如上所述。您还可以查看我更新的github存储库。该项目在Windows本地正常运行（本地未使用gunicorn）。

我的个人档案：

web: gunicorn run_app:app
worker: python /app/.heroku/python/bin/huey_consumer run_huey.huey

我以前遇到错误Failed to find application object 'app' in 'run_app'。我试图通过将run_app.py更改为以下内容来解决此问题：

from app import create_app, config

if __name__ == '__main__':

    import logging
    logging.basicConfig()
    logging.getLogger().setLevel(logging.DEBUG)

    app = create_app()
    app.run(host='localhost', port=6060, debug=True)


else:


    app = create_app()
    app.run(debug=False)

不幸的是，现在当我按下heroku时，我看到了：

我该如何解决？

Answer 1

您试图将应用程序绑定到的端口已被另一个应用程序使用。关闭另一个应用程序，然后重新部署

Answer 2

尝试在 Heroku 上运行 Flask 应用程序时遇到了同样的错误，并通过删除了

app.run

完全来自我的应用程序文件的声明（我的应用程序文件名为 app.py），例如您的 run_app.py。

我的档案：

web: gunicorn -b 0.0.0.0:$PORT app:app

当我想在本地运行应用程序时，我在终端（MacOS zsh）中运行

FLASK_ENV=development flask run
