我正在尝试运行这个Python Heroku教程中的hello.py。在运行
然而,当我重新运行
任何帮助都将不胜感激。提前致谢。
foreman start
命令后,我的问题开始了。即使我已经安装了Heroku Toolbelt,我仍然收到以下错误消息:
foreman不被识别为内部或外部命令、可执行程序或批处理文件。
因此,我将foreman文件(版本0.63.0)的位置添加到了我的path中:
C:\Program Files (x86)\Heroku\ruby-1.9.2\bin
并重新启动了命令提示符并重新运行foreman start
。现在,我收到以下错误消息:

阅读了this answer之后,我进行了如下操作:
gem uninstall foreman
gem install foreman -v 0.61.0
然而,当我重新运行
foreman start
时,现在出现了这个错误。(venv) C:\Users\me\Desktop\Code\heroku_python_app>foreman start
