如何解决《使用rails尝试angularjs时出错:未定义方法`register_engine'代表nil:NilClass(NoMethodError)》经验，为你挑选了1个好方法。
我是angularjs和rails的新手.在我的新公司中,我们必须在带有角度的轨道上使用红宝石.在单独使用railsjs和ruby on rails的教程之后,我正在尝试使用以下链接将两者结合起来:https:
//thinkster.io/angular-rails#generating-activerecord-models
完成所有步骤后直到主题"当我运行rails s命令时,将前端与资产管道集成"(包括本主题中的步骤)会出现以下错误:
=> Booting WEBrick
=> Rails 4.2.5 application starting in development on http://localhost:3000
=> Run `rails server -h` for more startup options
=> Ctrl-C to shutdown server

使用rails版本4.2.5
以下是Gemfile的片段:
source 'https://rubygems.org'
gem 'angular-rails-templates'
gem 'rails', '4.2.5'
gem 'sqlite3'
gem 'sass-rails', '~> 5.0'
gem 'uglifier', '>= 1.3.0'
gem 'jbuilder', '~> 2.0'
gem 'sdoc', '~> 0.4.0', group: :doc
group :development, :test do
gem 'byebug'
end
group :development do
gem 'web-console', '~> 2.0'
gem 'spring'
end

我遇到过同样的问题.这是一个与'链轮'有关的问题.尝试安装旧版本添加gem 'sprockets', '2.12.3'到您的gem文件,然后通过运行更新您的gem bundle update.它对我有用.

2.12.4也为我解决了问题,但没有以下内容:3.0.3,3.1.0,3.2.0,3.3.5,3.4.1.3.5.2.顺便说一句,我没有使用AngularJS.
