Rails 5 DEPRECATION警告：通過常量訪問MIME類型已被棄用

Question

已安裝的Rails 5.認爲事情沒有問題，但無法創建數據庫或啓動服務器。我得到這個錯誤：

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)

不太確定在這裏做什麼。不知道在哪裏改變Mime::HTML。任何想法，爲什麼我得到這個錯誤？或者如何解決它？

Answer 1

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

Answer 2

改變寶石web-console不能解決問題。

現在有幾個月開放的gem內部有更改請求。在解決問題之前，您可以採取this叉具有警告顯示的變化。
