Unsupported protocol null for file paths

[moll]

Hey,

I'm trying to see if npm-shrinkwrap fixes NPM's problems related to shrinkwrapping projects that have modules installed from either a tarball or an unpacked directory. Seems that it dies outright instead.

That is, with modules installed from ./vendor/foo.tgz or from ./modules/foo, npm-shrinkwrap dies with unsupported protocol null.

Cheers

@moll Interesting. I have never tried installing from tarballs before.

A contribution to support tarballs is welcome :)

I found that upgrading NPM to at least v2.3.0 fixes another issue I was having that made me look into this project. Sorry, for now I'll remain using with the built-in shrinkwrapping. :-)

Feel free to do what you deem most useful with this issue report. ;-)

We're using local directories with the file: protocol. I've created #81 which fixes the problem for directories and should work for tarballs too (although I haven't actually tested that yet)
