Cannot read property 'tarball' of undefined, version data absent

Not sure why, but this error just began on my project out of seemingly thin air.

warn Error on download for npm:ansi-styles

ansi-styles is the first package that my build process actually finds it wants to download, so I guess I might also fail on package 2, 3 etc. as well.

The parameters coming in to the download function are:

• repo: 'ansi-styles'
• version: '^2.1.0'
• hash: ""
• versionData: { }

This was first reported to me around 1:15 pacific time on a build that seemed fine yesterday and I believe was fine earlier today as well.

By the way, the call out of registry.js on line 117 seems to be passing:

self: {"ui":{"logLevel":3,"format":{}},"name":"npm","tmpDir":"/Users/dmaddox/.jspm/npm-cache","remote":"https://npm.jspm.io","strictSSL":true,"alwaysAuth":false,"versionString":"jspm-npm@0.26"}
args: {"0":"ansi-styles","1":"^2.1.0","2":"","3":{},"4":"/Users/dmaddox/.jspm/packages/npm/ansi-styles@^2.1.0"}

which seems strange. It really should be looking to npm, not my cache. I already cleaned my cache, fwiw.
