heroku db：pull错误

Question

Well, I used to be able to push and pull with heroku, but it just asked me to upgrade taps, so I did. Once I did that I started getting errors that look like this when I attempt a db:pull

Eventually I ended up trying to upgrade everything in sight, including:
sequel
heroku
rubygems
and of course taps
