pg:pull 之后的 Heroku ruby​​ 错误

Question

我使用heroku 几个月来完全没有任何问题。

今天我尝试制作一个本地数据库以将服务器端与开发分开。我按照教程安装了 PG，然后使用了 heroku pg:pull 命令。它似乎做了一些事情（它确实做到了：在本地创建了一个新数据库，但没有架构和表——可能是因为我使用了命名架构，而不是默认架构？）。

在 pg:pull 终止后，我无法再启动任何 heroku 命令。我明白了：

我尝试重新安装heroku toolbelt，但没有结果。

我正在使用 Windows。

有人知道如何解决吗？

感谢所有的建议和回答！

它变成了 Heroku Toolbelt 的一个简单的损坏版本。他们回滚了，我重新安装了 Heroku。它解决了这个问题。
