ruby-on-rails - 警告 : circular argument reference - now when trying to open rails console

Question

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，这样我就可以使用 Rails 控制台。我在 Rails 版本 3.2.13 上。

我遇到了同样的问题。这是由于 对 gem 文件的错误访问权限 引起的。这些 gem 归错误的用户所有。

这为我解决了问题:

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

不幸的是，我没有使用。因此，我无法为您提供有关如何为 rvm 执行此操作的详细说明。
