在全新安装时运行 rails 或 rake 命令时出错答案

【问题标题】：Error when running rails or rake command on fresh install在全新安装时运行 rails 或 rake 命令时出错
【发布时间】：2011-10-15 14:21:06
【问题描述】：

macbook air 昨天买的。安装了自制软件、xcode、rails、git，很好地克隆了我的项目。运行“rails s”或 rake db:create、rake db:migrate 等都会返回同样的错误。已运行捆绑安装。看起来很奇怪，可能需要重新安装，但我应该重新安装什么？

【解决方案1】：

我没有 ruby 1.9.2。 ——只是没有注意到。无论如何，做了明智的事情并通过 rvm 安装，现在一切都已启动并运行。

【解决方案2】：

我之前的答案被删除了，因为我在问如果我不能更新到 1.9.x 应该怎么做，因为接受的答案并没有真正解决问题。

顺便说一句，我向 frontend-helpers 提交了一个补丁，该补丁现已合并到 master 中：

https://github.com/christopherhein/frontend-helpers/commit/b2ce595d2dd183b643fbe4c3c22cd9defbc24ed7

因此，如果您遇到此问题，只需升级您的 Gemfile！
