我的 Rails 应用程序没有运行,并且出现错误:
cannot load such file -- safe_yaml/transform/to_symbol (LoadError)
我不知道为什么会出现这个错误。当我删除 gem 'safe_yaml' 时,它给出了错误:
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:
cannot load such file -- safe_yaml/transform/to_symbol (LoadError)
谁能告诉如何解决这个问题?
谢谢
