Question

我正在使用图片进行CRUD ..当我在视图中显示图像时遇到错误“产品中的ExecJS :: ProgramError #index TypeError：对象不支持此属性或方法”

问题：如何在视图中显示我的图像？那是为什么？

注意：我的朋友没有安装像imagemagik＆amp;回形针..我还试图在我的视图（资产/图像文件夹）中显示静态图像并且它不起作用

# 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。降级宝石应该解决它。

找到您的coffee-script-gem并更改以下内容：

gem 'coffee-script-source', '1.8.0'

然后运行：

bundle update coffee-script-source

*如果此解决方案不起作用，请检查错误指向的位置（文件和行），并更新您的问题。
