Question

我开始玩Heroku在他们的免费计划中部署一个简单的Node.js。但是当我运行foreman start时，我看到了这个错误：

/Library/Ruby/Site/1.8/rubygems/builder.rb:10: undefined method `load_yaml' for Gem:Module (NoMethodError)
    from /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/rubygems.rb:1110:in `require'
    from /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/rubygems.rb:1110

    from /usr/local/foreman/lib/foreman/process.rb:2

    from /usr/local/foreman/lib/foreman/cli.rb:3
    from /usr/bin/foreman:13:in `require'
    from /usr/bin/foreman:13

问题：我对Ruby平台几乎一无所知，我不使用。我碰巧在我的机器上安装了rvm，因为我曾经想玩Octopress（基于Jekyll的博客生成器）。我第一次搜索互联网，但找不到任何东西。我还访问了官方的RVM站点并按照故障排除的基本步骤进行了操作：我运行了rvm stable（它没有产生任何输出...），确保对我的~/.bash_profile中的RVM脚本的调用是最后的，并且是的我正在使用bash。

以下是我可以提供的信息，以便您可以帮助我。

我在OS X 10.6.8下。

rvm list打印：

rvm rubies

Answer 1

PATH未正确设置，我的猜测是你重置或预设路径，使用ruby使其正常工作：

rvm use 1.9.2-p290

并安装工头：

gem install foreman

Ruby错误：使用Heroku的工头启动时Gem：Module（NoMethodError）的未定义方法`load_yaml'
