Ruby on rails 在ruby/rails中使用rake并在解析YAML时出错

我是Ruby/Rails新手，正在从事一个项目，设计一个在框架内使用mysql数据库的网页。我在让rails正常工作方面遇到了很多问题，但我敢肯定其中一个问题是Rake。当我运行命令时

    rake db:create:all

    rake -v

它返回大约300行，然后ruby解释器崩溃

我主要关心的是当我运行命令时

    rake db:create:all

    rake -v

我明白了

。。。
雷克流产了！
（）无法分析第17行第14列的YAML

YAML只是更大问题中的一小部分。我只是不知道为什么rake根本不起作用

在boot.rb中添加以下代码片段在require'rubygems'之后如何，我认为这是因为rubygems使用的yaml解析器是psych，而rails需要syck：

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