问题
I previously had my Heroku's application name at:
shielded-meadow-9293.heroku.com
This was the name when I created the Heroku remote and fired up the dyno. After everything was running smooth, I changed the name to
platformdesignmadness.heroku.com
The site works, but in the same terminal, when I do a command such as
heroku ps
I get a $> ! Couldn't find that app. error. Why is this?
回答1:
In your terminal:
git remote rm heroku
git remote add heroku git@heroku.com:yourappname.git
See here
Heroku docs here.

For all the people showing up here trying to figure out why a
$ heroku run:detached python script.py -n yyy -a zzzz
command isn't working, and giving this error:
▸ Couldn't find that app.
it's because Heroku senses the -a argument as the app name. To ignore these the fix is this, basically adding a --:
$ heroku run:detached -- python script.py -n yyy -a zzzz
and now it will work properly.
