我正在尝试从这个 Python Heroku 教程运行hello.py。运行此命令后我的问题开始了：. 即使我安装了Heroku Toolbelt ，我也收到以下错误：foreman start
工头不是内部或外部命令、可运行程序或批处理文件
所以我将工头文件（版本 0.63.0）的位置添加到我的路径中：
C:\Program Files (x86)\Heroku\ruby-1.9.2\bin
并重新启动命令提示符并重新运行foreman start。现在，我收到此错误：

阅读此答案后，我执行了以下操作：
gem uninstall foreman
gem install foreman -v 0.61.0
但是，当我重新运行时，foreman start我现在收到此错误
(venv) C:\Users\me\Desktop\Code\heroku_python_app>foreman start
14:13:20 web.1 | started with pid 252
