yarn should show currently installed versions of modules on the system

[NonPolynomial]

Do you want to request a feature or report a bug?

Feature

What is the current behavior?

yarn has no command to show information about the currently installed versions of node etc.

What is the expected behavior?

I expect that yarn has a command which shows information / versions of installed node like npm version

maybe yarn versions because yarn version has another purpose.

_expected output_:

$ npm version
{
  npm: '3.10.5',
  ares: '1.10.1-DEV',
  http_parser: '2.7.0',
  icu: '57.1',
  modules: '48',
  node: '6.3.0',
  openssl: '1.0.2h',
  uv: '1.9.1',
  v8: '5.0.71.52',
  zlib: '1.2.8' 
}

$ yarn versions
{
  yarn: '0.16.0',
  ares: '1.10.1-DEV',
  http_parser: '2.7.0',
  icu: '57.1',
  modules: '48',
  node: '6.3.0',
  openssl: '1.0.2h',
  uv: '1.9.1',
  v8: '5.0.71.52',
  zlib: '1.2.8' 
}

Please mention your node.js, yarn and operating system version.
Node: 6.3.0
Yarn: 0.16.0
OS: Win 8.1

Created #1423 to fix this, pending approval.

no, thats the same to npm ls.
npm version instead shows the installed versions of e.g. Node and NPM.

changed the title of that issue
