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？

您不想使用生产环境以生产模式启动服务器吗？

rails server -e production

rails 控制台环境和 rails server -e 环境的语法差异有点像 PITA

在控制台生产的情况下指定环境，在服务器的情况下它指定其他东西（可能使用哪个服务器 webrick/...）。

因此，如果您想指定环境，请执行以下操作：

ENV=production rails server
