我想在YAML中重用哈希

Defaults: &defaults
  Company: Foo
  Item: 123

Computer: *defaults
  Price: 3000

但是,这会产生错误。

是分别定位每个字段值的唯一途径是这样

Defaults:
  Company: &company Foo
  Item: &item 123

Computer:
  Company: *company
  Item: *item
  Price: 3000

尝试通过导入重新使用完整的组:

Defaults: &defaults
  Company: foo
  Item: 123

Computer:
  <<: *defaults
  Price: 3000
