在dreamhost问题上部署Rails应用程序
所以我对这个感到茫然。 我的错误是：
缺少这些必需的gem：jrails你正在运行：ruby 1.8.7.72 at /usr/bin/ruby1.8 rubygems 1.3.6 at /home/ryann/.gem/ruby/1.8,/ usr / lib / ruby / gems / 1.8运行rake gems:install以安装缺少的gem。
我在供应商目录中解压缩了jrails并冻结了我的本地rails环境。 在我的本地机器上一切正常。
我在environment.rb文件中使用config.gem’jrails’。
我的踪迹是（抱歉这个烂摊子）：

任何人都知道为什么我在打开包装后仍然错过了一个gem？
问题出在共享主机上。 在那里，您通常只为您拥有所有用户和本地目录中的常用gems存储库。 可以通过在config / preinitializer.rb或config / environment.rb中指定正确的路径来解决此问题
ENV['GEM_PATH'] = '/home/[username]/ruby/gems:/usr/lib/ruby/gems/1.8' Gem.clear_paths
这是我托管的路径结构，您可能需要为您更新它。
编辑
检查了我的来源，您可能还需要在这些行之前添加：
require 'rubygems' require 'rubygems/gem_runner'
