在此上下文中不允许使用Capistrano映射进行部署时出现psych.rb错误

我正在尝试将Rails应用程序部署到CentOS 6 / nginx / passenger服务器，但是cap部署：冷却给我一个错误。 以下是部署输出的相关部分：

Rails 3.2.1。

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？ 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。

我已经尝试通过各种在线validation器来设置manifest.yml文件的上下文 – 它很好。 据我所知，没有遗漏空格或标签。

谢谢！

Answer 1

我有这个问题并删除myapp/shared/assets下的.json清单文件，如此处所示 （实际上，他们建议重命名它们，但这对我不起作用）。

Answer 2

我解决了这个问题 因为Capistrano的deploy/assets.rb的文件使用了YAML.load所以调用了Psych。

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 。 修正.bashrc错误，一切都很好！
