我已经构建了一个监听webhook的node.js应用程序。目前，它用于构建jekyll网站。

我已经在服务器上配置了它，并且jekyll build在jekyll网站（正在发送钩子）的根目录中运行它时，它可以完美运行。当我在外壳中的ssh上运行node.js应用程序时，当触发git钩子时，一切也都可以正常工作。

但是，当从新贵的脚本（如下所示）运行node.js应用程序时，似乎找不到该gems。它一直在询问我确定已安装的依赖项（全局以及针对我的用户）。

在我放入的脚本中echo`which jekyll`，这表明它确实指向本地安装的jekyllbin ：/home/christophe/.gem/ruby/2.0.0/bin/jekyll。但是在此之下，我执行jekyll命令，但它失败了：

/usr/lib/ruby/2.0.0/rubygems/dependency.rb:296:in `to_specs': Could not find 'jekyll' (>= 0) among 31 total gem(s) (Gem::LoadError)
    from /usr/lib/ruby/2.0.0/rubygems/dependency.rb:307:in `to_spec'
    from /usr/lib/ruby/2.0.0/rubygems/core_ext/kernel_gem.rb:47:in `gem'
    from /home/christophe/.gem/ruby/2.0.0/bin/jekyll:22:in `<main>'

如何执行此bash脚本以正确执行jekyll？

请注意，GEM_PATHS缺少第二个条目中的主目录前缀。我已经尝试通过放入env GEM_PATH="/home/christophe/.gem/ruby/2.0.0"新贵的脚本来解决此问题，但这并没有改变任何内容。

同时，我已经通过手动将deps列表作为root来解决了。但是，我认为这不是一个好方法，因为暴发户正以我的用户身份明确运行。其次，该软件需要在没有root权限的服务器上运行。所以我仍然想知道解决方法。
