Question

我正在尝试在Travis-CI上从github构建我的Ruby on Rails项目，但我遇到了迁移问题。它为迁移运行了一个rake任务，但它在此之后抱怨了相同的迁移步骤。

它跟随我的.travis.yml文件：

language: ruby
rvm:
  - 1.9.2
before_script:
  - "rake db:migrate RAILS_ENV=test"

这是构建输出：

Answer 1

当我试图让我的Rails 3.2应用程序与Travis CI一起工作时，

This blog post给了我极大的帮助，并写了一个实际有效的.travis.yml文件。这是我的参考，所以希望它有所帮助：

<强> .travis.yml

language: ruby
rvm:
  - 1.9.2
  - 1.9.3
env:
  - DB=sqlite
  - DB=mysql
  - DB=postgresql
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'
  - psql -c 'create database my_app_test' -U postgres
bundler_args: --binstubs=./bundler_stubs

Answer 2

而不是运行rake db:migrate RAILS_ENV=test运行rake db:test:prepare。

这是因为rake db:migrate将针对您的测试数据库运行所有迁移，如果您进行了大量迁移，这可能需要很长时间。 db:test:prepare任务不会这样做，而是只使用db/schema.rb中的模式设置测试数据库。

试一试，看看是否有效。

Answer 3

为我解决问题的解决方案是： rake db:schema:load代替rake db:migrate RAILS_ENV=test

rake db：迁移不适用于travis-ci构建
