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N-Y-N-Y.)
更多信息：bundle exec rails console失败,原因是服务器上没有安装sqlite3 gem.但是,bundle exec rails服务器生产失败,而且跟踪的可理解程度要低得多：
$bundle exec rails server production Exiting /home/spkspike/www/spike.sampablokuper.com/releases/20120530134819/vendor/ruby/1.9.1/gems/rack-1.4.1/lib/rack/handler.rb:63:in `require': cannot load such file -- rack/handler/production (LoadError) from /home/spkspike/www/spike.sampablokuper.com/releases/20120530134819/vendor/ruby/1.9.1/gems/rack-1.4.1/lib/rack/handler.rb:63:in `try_require' from /home/spkspike/www/spike.sampablokuper.com/releases/20120530134819/vendor/ruby/1.9.1/gems/rack-1.4.1/lib/rack/handler.rb:16:in `get' from /home/spkspike/www/spike.sampablokuper.com/releases/20120530134819/vendor/ruby/1.9.1/gems/rack-1.4.1/lib/rack/server.rb:269:in `server' from /home/spkspike/www/spike.sampablokuper.com/releases/20120530134819/vendor/ruby/1.9.1/gems/railties-3.2.3/lib/rails/commands/server.rb:59:in `start' from /home/spkspike/www/spike.sampablokuper.com/releases/20120530134819/vendor/ruby/1.9.1/gems/railties-3.2.3/lib/rails/commands.rb:55:in `block in <top (required)>' from /home/spkspike/www/spike.sampablokuper.com/releases/20120530134819/vendor/ruby/1.9.1/gems/railties-3.2.3/lib/rails/commands.rb:50:in `tap' from /home/spkspike/www/spike.sampablokuper.com/releases/20120530134819/vendor/ruby/1.9.1/gems/railties-3.2.3/lib/rails/commands.rb:50:in `<top (required)>' from script/rails:6:in `require' from script/rails:6:in `<main>'
解决方法
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
