ruby-on-rails - Travis CI hstore 不存在错误

Question

我收到来自 Travis 的错误消息:

The command "RAILS_ENV=test bundle exec rake db:migrate --trace" exited with 0.
$ bundle exec rake db:test:prepare
rake aborted!

我已经设置了以下迁移:

class SetupHstore < ActiveRecord::Migration
  def self.up
    execute 'CREATE EXTENSION hstore'
  end
  def self.down
    execute 'DROP EXTENSION hstore'
  end
end

因为它不起作用，我还添加了 CREATE EXTENSION hstore 和 belo Travis 配置:

language: ruby
rvm:
  - 2.0.0
env:
  - DB=postgresql
script: 
  - RAILS_ENV=test bundle exec rake db:migrate --trace
  - bundle exec rake db:test:prepare
  - bundle exec rspec spec/
before_script:
  - cp config/database.travis.yml config/database.yml
  - psql -c 'create database virtual_test' -U postgres
  - psql -c 'CREATE EXTENSION hstore' -U postgres
bundler_args: --binstubs=./bundler_stubs
before_install:
  - bundle update debugger-ruby_core_source

发生这种情况是否有原因？

Answer 1

您的配置文件指向三个不同的数据库，“postgresql”、“postgres”和“virtual_test”。

将测试更改为使用“postgres”数据库，不要费心创建 virtual_test 数据库，并确保通过 psql -d postgres -U postgres -c 'CREATE 在正确的位置创建 hstore扩展 hstore;'
