Rails 3.2 rake资产：预编译错误

Question

在rails 3.2中预编译资产管道时，我总是收到错误。我用rake资产看到的：预编译如下。

Tasks: TOP => assets:precompile 

我的application.css和.js分别有以下几种; 的.css

>*= require overcast 
>* =require jqgrid 
>*= require_self 
>*= require_tree . 

的.js

>//= require jquery 
>//= require jquery_ujs 
>//= require jquery-ui 
>//= require jqgrid-ja 
>//= require bootstrap 
>//= require_directory . 

我的Gemfile

source 'https://rubygems.org' 

gem 'rails', '3.2.3' 
gem 'bootstrap-sass', '2.0.2' 
gem 'bcrypt-ruby', '3.0.1' 

# Bundle edge Rails instead: 
# gem 'rails', :git => 'git://github.com/rails/rails.git' 

group :development, :test do 
# gem 'sqlite3', '1.3.5' 
    gem 'pg', '0.12.2' 
    gem 'rspec-rails', '2.9.0' 
    gem 'guard-rspec', '0.5.5' 
    gem 'annotate', '~> 2.4.1.beta' 
end 
group :test do 
    gem 'rspec-rails', '2.9.0' 
    gem 'capybara', '1.1.2' 
    gem 'guard-spork', '0.3.2' 
    gem 'spork', '0.9.0' 
    gem 'factory_girl_rails', '1.4.0' 
    gem 'cucumber-rails', '1.2.1', require: false 
    gem 'database_cleaner', '0.7.0' 
end 
group :production do 
    gem 'pg', '0.12.2' 
end 

# Gems used only for assets and not required 
# in production environments by default. 
group :assets do 
    gem 'sass-rails', '3.2.4' 
    gem 'coffee-rails', '3.2.2' 
    gem 'uglifier', '1.2.3' 
    gem "rails-asset-jqueryui" 
    gem "rails-asset-jqgrid" 
end 

gem 'jquery-rails', '2.0.0' 

有谁会对我为什么不能成功预编译的想法？

Answer 1

将rake添加到您的gem文件。 Ruby的stdlib包含一个老版本的rake。

gem 'rake', '~> 0.9.2' 

用bundle exec调用耙子以确保正在使用正确的版本。

bundle exec rake assets:precompile
