IO.js 2.2 build/SSL issue for Travis CI

[vitaly-t]

The latest version of Bluebird doesn't build on Travis CI any more, with IO.js 2.2:

WARNING: checksums are currently disabled for io.js
Now using io.js v2.2.0
$ node --version
v2.2.0
$ npm --version

$ nvm --version

Note this line: npm ERR! SSL Error: https://registry.npmjs.org/bluebird does not support SSL

Any idea why this is happening?

This is an issue with npm and/or io.js.

I was about to reply that I thought the same :) But lots of people are about to run into the same trouble, with the recent updates :)

yes but there is literally nothing that is relevant to bluebird here or nothing that bluebird could do
