我真的明白这意味着什么——帮助？

【问题讨论】：

尝试改变事物，看看会发生什么。尝试再次浏览指南，看看是否有帮助。然后，如果您仍然无法获得它，请告诉我们您尝试了什么，什么没有奏效。如果你表现出努力，人们更有可能提供帮助。另外，如果可以的话，通常避免“整个日志：”，同时仍然提出一个完整的问题。浏览这篇文章，它将帮助您改进您的问题：***.com/help/mcve

PTY 和 shell 请求消息意味着服务器不愿意为您启动交互式会话。这对 Heroku 来说可能是正常的。您链接到的 Heroku 页面正在讨论使用 ssh 进行 git 访问，这不需要 PTY 或 shell。是什么让您认为 shell 访问应该有效？

【参考方案1】：

您可以通过首先安装heroku toolbelt ssh 进入heroku dyno，然后在登录工具带后，您可以运行heroku run bash --app your_app_name

请参阅here 了解有关它的 heroku 文档。注意他们的警告，虽然说使用 ssh 没有什么好处
