我正在做图像的CRUD ..我遇到错误“ExecJS :: ProgramError产品＃索引TypeError：对象不支持此属性或方法”当我在我的视图中显示图像
问题：在我看来，我应该如何展示自己的形象？ 这是为什么？
注意：我的朋友没有安装任何像imagemagik＆paperclip ..我也试图在我的视图（assets / images文件夹）中显示一个静态图像，它不工作

# This file is auto-generated from the current state of the database. Instead # of editing this file,please use the migrations feature of Active Record to # incrementally modify your database,and then regenerate this schema deFinition. # # Note that this schema.rb deFinition is the authoritative source for your # database schema. If you need to create the application database on another # system,you should be using db:schema:load,not running all the migrations # from scratch. The latter is a flawed and unsustainable approach (the more migrations # you'll amass,the slower it'll run and the greater likelihood for issues). # # It's strongly recommended that you check this file into your version control system.

该错误通常与Windows的CoffeeScript兼容性问题有关。 降级宝石应该可以解决这个问题。
找到您的coffee-script-gem并将其更改为以下内容：
gem 'coffee-script-source','1.8.0'
然后运行：
bundle update coffee-script-source
*请检查错误指向（文件和行）如果此解决方案不起作用，并更新您的问题。
