问题描述

更新宝石后，我得到了这个:

After updating the gems I've got this:

ruby-1.9.2-p136导轨 3.0.3

ruby-1.9.2-p136 rails 3.0.3

尝试重新安装 gem RedCloth，没有用，系统只想使用 4.2.3 版本

Tried to reinstall gem RedCloth, didn't help, system wants to use only 4.2.3 version

知道如何修复它吗?谢谢

Any idea how to fix it? Thanks

推荐答案

您在某处有无效的 YAML 代码.我的意思是对 Psych(新的 ruby​​ YAML 解析器)无效.

You have invalid YAML code somewhere. I mean invalid for Psych (the new ruby YAML parser).

如果您不能(或不想)修复您的 YAML 代码，请尝试加载旧的 YAML 解析器 (syck)，将其添加到 config/boot.rb 的开头>

If you cannot (or don't want to) fix your YAML code, try to load the old YAML parser (syck), adding this at the beginning of config/boot.rb

require 'yaml'
YAML::ENGINE.yamler = 'syck'

这只是一个快速而肮脏"的修复，我知道

It's just a 'quick and dirty' fix, I know
