Rails:无法加载此类文件 -- safe_yaml/transform/to_symbol (LoadError) [英] Rails: cannot load such file -- safe_yaml/transform/to_symbol (LoadError)

问题描述

我的 rails 应用程序没有运行，并且出现错误:

My rails app is not running and i am getting error:

  cannot load such file -- safe_yaml/transform/to_symbol (LoadError)

我不知道为什么会出现此错误.当我删除 gem 'safe_yaml' 时，它给出了错误:

I dont know why this error is coming. When i remove gem 'safe_yaml', it gives error:

 Could not find safe_yaml-0.9.4 in any of the sources (Bundler::GemNotFound)

当我安装 gem safe_yaml-0.9.4 时，它给出:

When i install gem safe_yaml-0.9.4, it gives:

 cannot load such file -- safe_yaml/transform/to_symbol (LoadError)

谁能告诉如何解决这个问题?

Can anybody tell how to solve this?

谢谢

推荐答案

safe_yaml 版本存在问题.

There was problem with safe_yaml version.

我有 rails-admin 0.4.9.为此，需要 safe_yaml 0.6.3，而 rails_admin 0.4.9 安装 safe_yaml 0.9.4.

I have rails-admin 0.4.9. For this, safe_yaml 0.6.3 is required where rails_admin 0.4.9 installs safe_yaml 0.9.4.

所以我在我的 gemfile 中单独包含了 safe_yaml 0.6.3 并删除了 safe_yaml 0.6.4.

So i included safe_yaml 0.6.3 in my gemfile separately and removed safe_yaml 0.6.4.

一切正常！！
