我正尝试在 Travis-CI 上从 github 构建我的 Ruby on Rails 项目，但我遇到了迁移问题。它运行一个用于迁移的 rake 任务，但它在之后提示相同的迁移步骤。

它遵循我的 .travis.yml 文件:

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

这是构建输出:

最佳答案

This blog post当我试图让我的 Rails 3.2 应用程序与 Travis CI 一起工作并编写一个实际工作的 .travis.yml 文件时，对我帮助很大。以下是我的供您引用，希望对您有所帮助:

.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
