I\'m trying to get Heroku toolbelt working and it\'s a total nightmare. The install runs successfully, but when I run heroku update I get:
$ heroku upda
Heroku support finally helped me fix this. Long story short, if you're having this issue, just run:
$ rm -rf ~/.heroku/client
Then reinstall the Heroku Toolbelt from http://toolbelt.heroku.com
If you want the long answer, here you go:
There appear to be some edge cases where update ended up with some incorrect data and it is somewhat more difficult to recover from this. If you first delete the ~/.heroku/client directory and subsequently run the installer you should end up with a working result.
