'heroku run rake db:migrate' gives error 'Cannot find module 'create-error-class'



I haven’t seen this error before, but the last couple of days I have been seeing this message. I get this problem in other rails projects where I have had no issues, and with databases that I have no problem with in the past, so I suspect that this is a cloud9 issue. This also occurred right about the same time as the disappearing rsa_key problem, although this might be coincidental.

I can ‘git push heroku master’ with no problem, but when it comes time to ‘heroku run rake db:migrate’ I get this:

heroku run rake db:migrate
! Error in heroku-run:
! Cannot find module ‘create-error-class’
! See /home/ubuntu/.heroku/error.log for more info.

The error log shows this:
‘less /home/ubuntu/.heroku/error.log’

would you mind showing your rails gemfile?

I think re-install the Heroku is a nice try.
Keep in mind that do backup before you do re-installation.

rm -rf ~/.heroku
heroku --version

Good luck.


I tried this …

wget -qO- https://toolbelt.heroku.com/install-ubuntu.sh | sh

It did not really help…


Maybe I ran this in the wrong directory… let me check.


Okay, this just started working again and I have NO IDEA WHY IT STOPPED or WHY IT STARTED to work…

At least it is working,


I’ve just tried to run it as root :-
sudo heroku run rake db:migrate

It worked for me :smiley:
