node-pre-gyp broken on node v8 / windows

[springmeyer]

When testing node-pre-gyp on appveyor with node v8 (v8.0.0 specifically gets pulled in and npm 5.0.0), things are terribly broken. Not really dug much yet, but looks related to npm install not working:

     Error: Cannot find module 'nopt'
          at Function.Module._resolveFilename (module.js:485:15)
          at Function.Module._load (module.js:437:25)

Could also be an appveyor oddity: appveyor reports Installing node 8.1.0 (x64)... but then next reports:

node --version
v8.0.0
npm --version
5.0.0

That seems off /cc @FeodorFitsner

Found this can be worked around by downgrading npm to 2.x

Oh, good catch with 8.1.0 package, thanks! It should be fixed now.
