ruby 版本 - ruby​​ 1.9.3p0（2011-10-30 修订版 33570）[x86_64-linux]

轨道版本 - Rails 3.2.6

宝石版本 - 1.8.15

操作系统 - Ubuntu 12.04

我确实跑来sudo gem install rubygems-update -v 1.8.24更新 ruby​​gems 版本

启动rails服务器后，出现异常

问题描述不足以说明可能导致异常的原因。但很明显，Ruby on Rails 是在 ruby​​ 1.8 而不是 1.9 下运行的。

我的建议是：

  • 安装以下 ruby​​ 版本管理工具之一。RVM或rbenv。他们将帮助您管理整个系统的 Ruby 版本，在不同项目之间切换 Ruby 版本。我个人更喜欢 rbenv，该站点列出了所有优点。

安装和配置您的项目或全局 Ruby 版本后： 1. 仔细检查您当前的 ruby​​ 版本ruby --version 2. 运行gem install bundler 3. 在项目根文件夹下运行bundle update

如果 RoR 的 Gemfile 配置正确，第二步应该可以安装所有的依赖。确保您已完成所有设置并完成数据库配置rake db:migrate
