Rails 5 DEPRECATION警告：通过常量访问MIME类型已被弃用

Question

已安装的Rails 5.认为事情没有问题，但无法创建数据库或启动服务器。我得到这个错误：

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. Please change:

Mime::TEXT

to:

Mime[:text] . (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. Please change:

Mime::URL_ENCODED_FORM

to:

Mime[:url_encoded_form] . (called from at /usr/local/rvm/gems/ruby-2.2.3/gems/web-console-2.2.1/lib/web_console/request.rb:7)

不太确定在这里做什么。不知道在哪里改变Mime::HTML。任何想法，为什么我得到这个错误？或者如何解决它？

Answer 1

变化的Gemfile： gem 'web-console', '~> 3.0' 包更新

Answer 2

改变宝石web-console不能解决问题。

现在有几个月开放的gem内部有更改请求。在解决问题之前，您可以采取this叉具有警告显示的变化。
