以前用过rails-settings-cached这个神器去管理网站设置的参数，非常好用，也没碰到过问题。

这次的新项目是基于 rails5.1，gem 安装以后，按照文档中的提示执行命令rails g settings:install，提示以下错误信息：

[user1@mac1 demo1 (master)]$ rails g settings:install

Could not find generator 'settings:install'. Maybe you meant 'config:install', 'test_unit:system' or 'scss:assets'
Run `rails generate --help` for more options.

搜索了网上，发现有人报告过同样的错误，后来华顺没有跟进了：https://github.com/huacnlee/rails-settings-cached/issues/54。

有人怀疑settings在新版本的 rails 中是保留关键字了，所以需要将模块改名称。请指教如何解决这个问题。谢谢！！
