Rails控制台与生产服务器上的服务器差异

Question

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(不是真的在生产中,谢天谢地!),我发现以下列出的命令如下:

????????????????????????????????????????????
? 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？(我原以为右列中的模式应该是NYNY.)

更多信息:由于服务器上未安装sqlite3 gem bundle exec rails console的可理解原因而失败.然而,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:如何最好地解决此错误？

Answer 1

您不想使用生产环境在生产模式下启动服务器吗？

rails server -e production

rails控制台环境和rails服务器-e环境之间的语法差异有点像PITA
