4.0.0-alpha.0 crashes on node 0.10

blessc crashes on node 0.10 with error:

./.bin/blessc

fs-promise/node_modules/any-promise/any-promise.js:33
  throw new Error('Must install one of: '+libs.join());
        ^
Error: Must install one of: es6-promise,promise,native-promise-only,bluebird,rsvp,when,q

It will work if there is some of the listed libraries is installed in node scope.

PR #74 should fix this.

Looks like our test runner was actually failing those tests but the error wasn't getting surfaced correctly fooling the CI into thinking that it passed.

Note the 0 exit code from Travis though you can see red 😢

I was hoping this would be a quick fix, but that does not appear to be the case. Thankfully the code coverage changes we made will surface this more quickly in the future.

Following the update of 4.0.0 to release, this is now occuring for us. The error occurs when running any bless function. E.g. blessc -v

When we roll back to 3.0.3 the error is no longer present.

I'm thinking Bless 4 will need to be on Node 4.0 and later. See #96.
