【问题描述】：

每当我在应用程序的根目录中输入 rails console 时，我都会得到：

任何阻止这种情况发生的方法，所以我可以使用 rails 控制台。我在 Rails 版本 3.2.13 上。

【问题讨论】：

您能指定您在控制台中输入的内容吗？
你在什么根目录下输入rails console？
我在为这个 Rails 教程构建的应用程序的根目录中。对不起，我只是在学习这门语言；我应该指定的。
ruby-forum.com/topic/6873211 是我在搜索该错误时发现的。看看那个讨论，它可能会有所帮助。让我们知道！我发现的其他参考资料似乎指向 Compass。你正在学习的教程是什么？您说的是“本教程”，但我没有看到您指的地方。
stackoverflow.com/q/27717309/485864 可能这是一个重复的问题。

【解决方案1】：

我遇到了同样的问题。这是由gem 文件的访问权限错误引起的。宝石归错误的用户所有。

这为我解决了问题：

递归设置正确的用户：chown -R user folder。
重新安装必要的 gem（可选。我这样做只是为了确保没有破坏任何东西）

很遗憾，我没有使用。因此，我无法为您详细说明如何为 rvm 执行此操作。
