Rails 3.2.1. Rails 3.2.1。
The manifest.yml file mentioned contains 'jquery.min.map' - is that what the 'mapping not allowed' part is referring to? 提到的manifest.yml文件包含'jquery.min.map' - 是什么'不允许映射'部分指的是什么？ If so, I can't work out how to stop jQuery trying to include this map file. 如果是这样，我无法弄清楚如何阻止jQuery尝试包含此映射文件。
I've tried putting that contexts of the manifest.yml file through various online validators - it's coming up fine. 我已经尝试通过各种在线验证器来设置manifest.yml文件的上下文 - 它很好。 No missing spaces or tabs as far as I can see. 据我所知，没有遗漏空格或标签。
Thanks! 谢谢！

I solved this. 我解决了这个问题 Psych was being called because the file in Capistrano's deploy/assets.rb uses YAML.load . 正在调用Psych，因为Capistrano的deploy/assets.rb的文件使用YAML.load 。
The variable it was loading was a 'capture' of a command line cat command, and because my .bashrc had a syntax error in it, it was capturing the output of that error and passing it to YAML.load , too. 它加载的变量是命令行cat命令的“捕获”，因为我的.bashrc有一个语法错误，它正在捕获该错误的输出并将其传递给YAML.load 。 Fixed .bashrc error and all is good! 修复.bashrc错误，一切都很好！
