我正在关注Syntax Highlighting Revised的RailsCasts剧集 . 我更新了我的ApplicationHelper,看起来像这样:
require 'redcarpet'
module ApplicationHelper
class HTMLwithPygments < Redcarpet::Render::HTML
def block_code(code, language)
Pygments.highlight(code, lexer:language)
end
end
def markdown(text)
renderer = HTMLwithPygments.new(hard_wrap: true, filter_html: true)
options = {
autolink: true,
no_intra_emphasis: true,
fenced_code_blocks: true,
lax_html_blocks: true,
strikethrough: true,
superscript: true
}
Redcarpet::Markdown.new(renderer, options).render(text).html_safe
end
end
但是,我的网络应用程序返回
Routing Error
uninitialized constant Redcarpet::Render
Try running rake routes for more information on available routes.
我'm using Rails 3.2.11 and Redcarpet responds fine in rails console. I' ve最初没有包含 require 'redcarpet'
但是我按照here上的说明进行了操作,但它没有帮助 .

我删除了我的
Gemfile.lock
并再次做了bundle install
,它完美无缺 .
