我已经开始了对基于 Debian Squeeze 的生产服务器的部署过程。我们一直在 MacOS 中开发这个 Rails 应用程序。
- Rails 是 3.2.8 版
- Ruby 版本为 1.9.3p194（2012-04-20 修订版 35410）[x86_64-darwin12.2.0]
我们从一开始就安装了 rvm，并且该应用程序在我的计算机上完美运行。
为了了解需要什么，然后使用 Capistrano 制作脚本，我从以下内容开始：
- 安装成功 Ruby。
- 成功安装 Rails。
- 安装 SQLite3。（我不会在生产中使用它）
- RVM 安装成功。
- 复制整个应用程序目录并在其中运行bundle install。
然后，运行rake以确保一切正常，出现以下错误：
rake aborted!

每个其他命令，例如rails server或rails console都会显示相同的错误。
