在此处输入图像描述

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。您还可以查看我更新的 github 存储库。该项目在 Windows 上本地运行没有问题（本地不使用 gunicorn）。

我的档案：

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

我之前收到一个错误Failed to find application object 'app' in 'run_app'。我试图通过将 run_app.py 更改为：

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，现在当我推到heroku时，我看到：

我怎样才能解决这个问题？

尝试在 Heroku 上运行 Flask 应用程序时遇到相同的错误，并通过删除

app.run

声明完全来自我的应用程序文件（我的名为 app.py），例如你的 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

您尝试将应用程序绑定到的端口已被另一个应用程序使用。关闭其他应用并重新部署
