Yarn: Transient error when running kpm install

[shayne]

KPM 0.4.0 produced this error, a subsequent run didn't have this issue. Both reported no lockfile found. There was no lockfile at the time.

$ node nodeModules.js install
fbkpm install v0.4.0

Closing this as it appears to be resolved? Let me know if this is still a transient issues and I'll try and look into it. It's not entirely clear how I'd attempt to reproduce this.

I see this sort of problem consistently with yarn:

> yarn
yarn install v0.15.1
