The pubviz tool appears to be failing on the current master branch for polymer:

Actually sorry, this doesn't happen on master (I forgot to rerun pub upgrade once I switched back to the master branch). I assume my .pub dir was in a weird state or something which caused this. (I deleted my .pub dir, tried to run pub upgrade but it failed due to version mismatches, and then tried to run pubviz). Seems like a better error would still be good for this case though.

@jakemac53 Yeah, I'm using list-package-dirs at the moment. If I was using pub deps we'd get an from pub up front that the lock file is out of date.

When I'm bored...or you're bored. 😺
