Travis CI + ruby​​ on Rails软件包安装

Question

我试图在我的公共github存储库中添加Travis VI 。要使用taglib-ruby用户，应在该系统上安装libtag1-dev软件包。所以我写了我的.travis.yml文件，如下所示

language: ruby
rvm:
  - 2.0.0

env:
  - DB=mysql
before_install:
  - sudo apt-get update
  - sudo apt-get install -y libtag1-dev
script:
  - RAILS_ENV=test bundle exec rake db:migrate --trace
  - bundle exec rake db:test:prepare
  - bundle exec rspec spec/
before_script:
  - mysql -e 'create database my_app_test'

但是特拉维斯总是通过告诉以下失败

Installing rack-cache 1.2
Installing rack-test 0.6.2
Installing rack-ssl 1.3.4

Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

You must have taglib installed in order to use taglib-ruby.
Debian/Ubuntu: sudo apt-get install libtag1-dev
Fedora/RHEL: sudo yum install taglib-devel
Brew: brew install taglib
MacPorts: sudo port install taglib
