Node changed their Url.parse command.

(node:56977) [DEP0170] DeprecationWarning: The URL ssh://git@github.com:XXXXXX/YYYYY.git is invalid. Future versions of Node.js will throw an error.

To fix this issue, npm changed their resolver not to use Url.parse: npm/npm-package-arg#141. Yarn 1 could do the same.

In future versions of node, yarn 1 will cease working for git urls of this kind - unless an alternate parser is used.

[Faq]

Looks like some will switch away from yarn when this will hit as error from Node side.
