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：
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.

这是我的命令行返回的内容：
