Heroku keys "Cannot read property 'run' of undefined"

Question

I'm trying to use the Heroku cli "keys" functions to upload a ssh key to my account. Unfortunately I run into the following error whenever I try to use any of the keys methods.

TypeError: Cannot read property 'run' of undefined
at Object.<anonymous> (C:\Users\Administrator\AppData\Local\heroku\tmp\heroku-script-292666295:14:4)

Any thoughts would be greatly appreciated.

Answer 1

After speaking with the Heroku support team we found that heroku update fixed the problem.

Answer 2

It seems, Heroku command facing trouble finding right version of ruby so its throwing the error.

Uninstall Heroku Toolbelt through Windows "Control Panel\Programs and Features" after successful uninstallation, delete C:\Program Files\Heroku folder as well.

And then reinstall Heroku Toolbelt and try to run the command. It should work.
