# 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.
ActiveRecord::Schema.define(version: 20170406144121) do
# These are extensions that must be enabled in order to support this database

推荐答案
该错误通常与 CoffeeScript 与 Windows 的兼容性问题有关.降级 gem 应该可以解决它.
The error is commonly related to a CoffeeScript compatibility issue with Windows. Downgrading the gem should solve it.
找到您的 coffee-script-gem 并将其更改为以下内容:
Locate your coffee-script-gem and change it for the following:
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.
*Please check where the error points to (file and line) if this solution doesn't work, and update your question.
