yarn info
显示有关软件包的信息。
yarn info <package> [<field>]
此命令将提取有关软件包的信息，并以树格式返回该信息。该软件包不必已在本地安装。
yarn info react
yarn info vx.x.x
{ name: 'react',
version: '15.4.0-rc.2',
description: 'React is a JavaScript library for building user interfaces.',
time: { modified: '2016-10-06T22:09:27.397Z', ... } ... }
此命令的默认报告样式是单引号序列化。若要发出有效 JSON 的行，请使用标准 --json 标志
yarn info react --json
{"type":"inspect","data":{"name":"react","time":{...}}}
{"type":"finished","data":417}
特定版本的信息
将 @[version] 附加到软件包参数以提供特定于该版本的信息
yarn info [email protected]

version: '15.3.0',
description: 'React is a JavaScript library for building user interfaces.',

选择特定字段
如果提供了可选字段参数，则仅返回树的该部分。
yarn info react description

或检查可用的版本
yarn info react versions
yarn info v1.1.0
[ '0.0.1',

如果指定字段属于嵌套对象，则返回子树
yarn info react time
yarn info vx.x.x
{ modified: '2016-10-06T22:09:27.397Z',
created: '2011-10-26T17:46:21.942Z', ... }
yarn info react time --json
