Heroku Web 服务器无法在本地启动

我在本地启动 heroku Web 服务器时遇到问题。这是我不断收到的错误消息：

PS C:\Users\Dragan\heroku_workspace\python-getting-started> heroku local

我正在遵循本教程中描述的每个步骤LINK https://devcenter.heroku.com/articles/getting-started-with-python#run-the-app-locally我在项目“python-getting-started”中安装了虚拟环境。我正在尝试从项目的根目录启动本地网络服务器。

有人可以帮我解决这个问题吗？

UPDATE_1：我已经安装了适用于 Windows 的 Heroku Toolbelt，并且安装了适用于 Python 的 Anaconda。

根据 Heroku 教程，请在 Windows 中尝试此操作，而不是heroku local:

heroku local web -f Procfile.windows
