我正在尝试在浏览器中运行我的rails应用程序的主页,但是当我运行页面时,我收到运行时错误,说“Current ExecJS运行时不支持ES5.请安装node.js”.

我该如何解决这个错误？

这是我的Gem文件：

source 'http://rubygems.org'


# Bundle edge Rails instead: gem 'rails',github: 'rails/rails'
gem 'rails','4.1.8'
# Use sqlite3 as the database for Active Record
gem 'sqlite3'
# Use SCSS for stylesheets
gem 'sass-rails','~> 4.0.3'
# Use Uglifier as compressor for JavaScript assets
gem 'uglifier','>= 1.3.0'
# Use CoffeeScript for .js.coffee assets and views
gem 'coffee-rails','~> 4.0.0'
# See https://github.com/sstephenson/execjs#readme for more supported runtimes
# gem 'therubyracer',platforms: :ruby

# Use jquery as the JavaScript library
gem 'jquery-rails'
# Turbolinks makes following links in your web application faster. Read more: https://github.com/rails/turbolinks
gem 'turbolinks'
# Build JSON APIs with ease. Read more: https://github.com/rails/jbuilder
gem 'jbuilder','~> 2.0'
# bundle exec rake doc:rails generates the API under doc/api.
gem 'bootstrap-sass'
gem 'sdoc','~> 0.4.0',group: :doc

# Use ActiveModel has_secure_password
# gem 'bcrypt','~> 3.1.7'

# Use unicorn as the app server
# gem 'unicorn'

# Use Capistrano for deployment
# gem 'capistrano-rails',group: :development

# Use debugger
# gem 'debugger',group: [:development,:test]

# Windows does not include zoneinfo files,so bundle the tzinfo-data gem
gem 'tzinfo-data',platforms: [:mingw,:mswin]
gem 'autoprefixer-rails','~> 5.0.0.2'

这是我的命令行返回的内容：

安装node.js gem的正确方法是什么？

解决方法

它不是宝石,你必须从 http://nodejs.org/安装node.js.
