尝试在本地预编译我的资产时,我得到以下信息
RAILS_ENV=production bundle exec rake assets:precompile
rake aborted!
Sprockets::NotImplementedError: Custom asset_path helper is not implemented
Extend your environment context with a custom method.
environment.context_class.class_eval do
def asset_path(path, options = {})
end
end
/Users/cman/.rvm/gems/ruby-2.2.2@jbd-ruby2.2.2/gems/sprockets-3.6.0/lib/sprockets/context.rb:198:in `asset_path'

我一生都无法弄清楚为什么会发生这种情况-任何有关如何解决的建议都将不胜感激!
更新
仅当我添加具有以下内容的初始化程序时,我才能进行预编译:
Rails.application.assets.context_class.class_eval do
def asset_path(path, options = {})
return ''
end
end
但是,如果我这样做,当我推送到我的暂存环境时,来自 Bootstrap 的字形图标有一个空路径,因此不会渲染:
font-face{font-family:'Glyphicons Halflings';src:url("");src:url("") format("embedded-opentype"),url("") format("woff"),url("") format("truetype"),url("")
更新 2
如果我将初始化程序修改为以下内容,我会在我的预编译引导资产中为 glypicons 获得一个路径,但它不是预编译的 Glyphicon 文件,而是非编译的资产路径:
Rails.application.assets.context_class.class_eval do
def asset_path(path, options = {})
#return ''
"/assets/#{path}"
end
end
@font-face{font-family:'Glyphicons Halflings';src:url("/assets/bootstrap/glyphicons-halflings-regular.eot");src:url("/assets/bootstrap/glyphicons-halflings-regular.eot?#iefix") format("embedded-opentype"),url("/assets/bootstrap/glyphicons-halflings-regular.woff") format("woff"),url("/assets/bootstrap/glyphicons-halflings-regular.ttf") format("truetype"),url("/assets/bootstrap/glyphicons-halflings-regular.svg#glyphicons_halflingsregular")
