安装Rails 5.认为事情很好,但无法创建数据库或启动服务器.我收到此错误：
DEPRECATION WARNING: Accessing mime types via constants is deprecated.
Please change:Mime::HTML
to:
Mime[:html] . (called from at
/usr/local/rvm/gems/ruby-2.2.3/gems/web-console-2.2.1/lib/web_console/request.rb:7)
DEPRECATION WARNING: Accessing mime types via constants is deprecated.

不太清楚在这做什么.不确定在哪里更改Mime :: HTML.关于我为什么会收到此错误的任何想法？或者如何修复它？
解决方法
更改Gemfile： gem’web-console’,’〜> 3.0′ 捆绑更新
