最近做了一个脚本。
后来又用 java 做了个界面。想用 java 调用脚本。
直接使用 ruby 脚本没有问题，再用 java 调用 ruby 脚本之后就出现问题了。

现在出现的问题是：

1.有好几个 ruby 文件。 java 调用其中一个文件 a.rb 后， a.rb 中 require 的 b.rb 就查找不到路径了，即时再同一个目录下
2.比如调用了本地的 pod ， a.rb 中有 require 'pod',结果也找不到 pod 。

脚本的开头部分:

require 'json'

require 'xcodeproj'
$LOAD_PATH.unshift(File.dirname(__FILE__))
require 'custom_add_system_framework.rb'
require 'LaunchImage.rb'

错误信息如下：

请问有过类似经验的同志们帮忙解决一下。

实在找不到解决办法了。

谷歌了半天也没什么结果。
