Rails 3 – ‘无法解析Yaml’
我不知道我做错了什么。 我尝试运行’rails c’，但它只是给了我一个错误。 它在10分钟前工作。 ：\

尝试在config / boot.rb的开头添加它
require 'yaml' YAML::ENGINE.yamler= 'syck'
仅供记录，YAML不接受标签作为缩进，它们必须是空格。 将标签更改为空格为我解决了^^
“无法解析Yaml”转到您的项目并看到附近的项目名称有一个！ sign.open it并查看发生了哪个文件冲突。右键单击该文件，选择Replace with then from Repository。对于所有文件，请更改代码。然后运行服务器它将起作用。
我在我的一个YAML文件中用不带引号的*发出了这个问题。

希望它会有所帮助。 🙂
