【问题描述】:
这似乎是一个重复的问题,但似乎没有一个解决方案适合我。我的 Gemfile 中有 gem jquery-rails。另外,线条
//= require jquery
//= require jquery_ujs
//= require turbolinks
//= require_tree .
这是我的 Gemfile:
source 'https://rubygems.org'
# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.2.1'
# Use SCSS for stylesheets
#gem 'sass-rails', '~> 5.0'
# Use Uglifier as compressor for JavaScript assets
gem 'uglifier', '>= 1.3.0'
# Use CoffeeScript for .coffee assets and views
#gem 'coffee-rails', '~> 4.1.0'
# See https://github.com/rails/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 '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
group :development, :test do
# Call 'byebug' anywhere in the code to stop execution and get a debugger console
gem 'byebug'
# Use mysql as the database for Active Record
gem 'mysql2'
# Access an IRB console on exception pages or by using <%= console %> in views
gem 'web-console', '~> 2.0'
end
# Windows does not include zoneinfo files, so bundle the tzinfo-data gem
gem 'tzinfo-data', platforms: [:mingw, :mswin, :x64_mingw, :jruby]
我的 application.html.erb :
<!DOCTYPE html>
<html>
<head>
<title></title>
<%= stylesheet_link_tag 'application', media: 'all' %>
<%= javascript_include_tag 'application' %>
<%= csrf_meta_tags %>
</head>
<body>
<%= yield %>
</body>
</html>
我无法启动我的 Rails 应用程序。我不明白是什么问题。我的红宝石版本是 2.1.6 请帮忙。
【问题讨论】:
-
您是否运行了捆绑安装?
-
是的,我已尝试捆绑安装并重新启动服务器。我不明白出了什么问题。
-
Rails 应该从 gem 加载 javascript 文件。尝试运行
bundle exec rails s以确保您使用的是正确的 gem。 -
我明白了。这是一个平台问题。需要将
<%= javascript_include_tag 'application' %>更改为<%= javascript_include_tag 'default' %> -
目前使用 Fedora 20。从 Gemfile 卸载 nodejs 并取消注释 rubyracer gem 就可以解决问题。仅当错误消息更清楚一点时。
