尝试使用Capistrano cap deploy部署我的项目：迁移,我在我的
database.yml上的测试别名中出错(这在本地服务器上运行正常)
development: database: db_dev adapter: MysqL2 username: xxxxxx password: xxxxxx host: localhost encoding: utf8 test: &test database: db_test adapter: MysqL2 username: xxxxxx password: xxxxxx host: localhost encoding: utf8 production: database: db_prod adapter: MysqL2 username: xxxxxxxx password: xxxxxxx host: localhost encoding: utf8 cucumber: <<: *test
控制台日志是：

解决方法
我不相信您可以根据您引导的环境分配测试,开发或生产别名(如果环境是生产环境,则将应用生产设置).问题是,如果这样做,黄瓜只能在测试环境中使用.
我使用了类似于下面的东西：
base: &base
adapter: MysqL2
host: address.com
encoding: utf8
adapter: MysqL2
username: xxxxxx
password: xxxxxx
development:
database: db_dev
<<: *base
test:
database: db_test
<<: *base
production:
database: db_prod
<<: *base
cucumber:
database: cucumber
<<: *base
