本文记录了一个Rails应用启动过程中遇到的问题及解决过程。作者在启动应用时遇到了与action_web_service相关的错误，通过排查依赖和gem安装情况最终解决了问题。

运行时奇怪的错误

网上的资料说缺少 gem

找出所有的 require 来

grep -rni '^require' ./*

对了N个小时还是不行

最后无意中 ruby script/console production 试了一下,看到了

`gem_original_require': no such file to load -- action_web_service (MissingSourceFile)

晕啊.就是它

打开

vi config/environment.rb

加一句

config.frameworks -= [ :action_web_service ]

当然你也可以

gem install actionwebservice

终于可以睡觉了

rails 新的版本已经没有 action_web_service
