metro 0.25.1 can not be used from npm

What is the current behavior? Can’t install metro@0.25.1 or have it as dependency.

If the current behavior is a bug, please provide the steps to reproduce and a minimal repository on GitHub that we can yarn install and yarn test.

mkdir fuck-metro && cd fuck-metro
npm init # all answers default
npm i -P metro@0.25.1 
npm ERR! code EUNSUPPORTEDPROTOCOL
npm ERR! Unsupported URL Type "npm:": npm:babylon@^7.0.0-beta

What is the expected behavior? Package metro should successfully be installed into node_modules and recorded in package.json

Please provide your exact Metro configuration and mention your Metro, node, yarn/npm version and operating system. OS: macOS Sierra 10.12.6 (16G1212)

npm --versions
{ 'fuck-metro': '1.0.0',
  npm: '5.6.0',
  ares: '1.13.0',
  cldr: '32.0.1',
  http_parser: '2.7.0',
  icu: '60.2',
  modules: '59',
  napi: '2',
  nghttp2: '1.29.0',
  node: '9.5.0',
  openssl: '1.0.2n',
  tz: '2017c',
  unicode: '10.0',
  uv: '1.19.1',
  v8: '6.2.414.46-node.18',
  zlib: '1.2.11' }

Error exactly here: packages/metro/package.json and it still in master.

And in case one can’t find it, I provide link to documentation of package.json format: https://docs.npmjs.com/files/package.json#urls-as-dependencies

@jeanlauliac Looks like solution, should I create pull request?

A way to fix this, I think, is to create a published package ex. metro-babylon7 that itself depends on babylon@7 and re-export it verbatim, then depend on babylon@6 and metro-babylon7 from metro.
