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
