在使用 RVM Ruby 1.9.3-p194 将一个非常基本的 Rails 3.2.3 试用站点部署到“生产”服务器（不是真正投入生产，谢天谢地！）后，我发现以下列出的命令是正确的：
╔══════════════════════════════════════╤═══╗
║ command issued │OK?║
╟──────────────────────────────────────┼───╢
║ bundle exec rails console │ N ║
║ bundle exec rails console production │ Y ║
║ bundle exec rails server │ Y ║
║ bundle exec rails server production │ N ║
╚══════════════════════════════════════╧═══╝
我的第一个问题：这是预期的吗？（我原以为右栏中的模式应该是 NYNY。）
更多信息：由于服务器上未安装sqlite3bundle exec rails console gem的可理解原因而失败。但是，失败的痕迹更难理解：bundle exec rails server production
$ bundle exec rails server production

我的第二个问题：如何最好地解决这个错误？
