Running Heroku Console does not start

Question

I am trying to run Heroku console, but in the console, I get the message "Running console attached to terminal" but the console doesn't start.

In the Heroku logs, I get the error:

 Error: no child processes attached.

Any help?

Answer 1

I just had a thread with Heroku support about my similar issue, here was their response, which worked for me.

So this is a bamboo app. You can either do

$ heroku console

which will tap into a running web dyno, or you can run a new console as a one-off process with:

$ heroku run bundle exec rails console

On cedar apps you'd also be able to do

$ heroku run console

which also starts a one-off process, because the console process type would be implied by the rails buildpack or declared in your Procfile. It amounts to the same as the previous line.

Answer 2

I was experiencing same issues.
Try

heroku run rails console

in Rails >=3

Happy coding :)
