Heroku_can't upgrade to Cedar-14

As requested on Heroku, I am trying to upgrade from Cedar-10 to Cedar-14, but in vain. On my console, When I execute

heroku stack:set cedar-14

I get this:

 `stack:set` is not a heroku command.

Even if I've already installed the latest version of heroku toolbelt as proposed there (I am on Windows), I get the same error message

Many thanks

Solution

  • It looks like your current heroku version isn't up to date.

    Things you can try:

    heroku update

    If that doesn't work

    gem uninstall heroku

    Reinstall the gem or the heroku toolbelt

    If that doesn't work:

    which heroku

    Delete the executable at the path listed by the above mentioned command

    After that reinstall the heroku toolbelt
