所以我部署到 heroku 并且我的 javascript 不存在。然而，css 编译得很好。
我的生产.rb
# Disable Rails's static asset server (Apache or nginx will already do this)
config.serve_static_assets = false
# Compress JavaScripts and CSS
config.assets.compress = true
# Don't fallback to assets pipeline if a precompiled asset is missed
config.assets.compile = true
我的 application.js 文件
// This is a manifest file that'll be compiled into including all the files listed below.
// Add new JavaScript/Coffee code in separate files in this directory and they'll automatically
// be included in the compiled file accessible from http://example.com/assets/application.js
// It's not advisable to add code directly here, but if you do, it'll appear at the bottom of the
// the compiled file.
//
//= require jquery
//= require jquery_ujs
//= require "bootstrap.js"
//= require "demo.js"
//= require "highcharts.js"
//= require_tree .
由于另一个问题因此得到解决，因此尝试使用和不使用 .js 扩展名。
heroku 日志中没有任何内容，在 heroku slug 创建期间没有错误。
有任何想法吗？
