`git push heroku master`失败，因为它使用了错误的电子邮件地址

Question

I created a rails app with

$ rails new appname
$ cd appname

I initialized it as a git repo

$ git init
$ git add .
$ git commit -m 'init'

I logged into heroku

$ heroku login
Email: correct@email.com
Password (typing will be hidden):

I created the heroku app

$ heroku create
Creating radiant-bayou-6540... done, stack is cedar
http://radiant-bayou-6540.herokuapp.com/ | git@heroku.com:radiant-bayou-6540.git
Git remote heroku added

I tried to push to heroku

$ git push heroku master
!  Your account incorrect@email.com does not have access to radiant-bayou-6540.

Wait what? I didn't log in with incorrect@email.com, I logged in with correct@email.com. Let's look at git

$ git config user.email
correct@email.com

What?! Why does heroku think I'm logging in with wrong@email.com

Your account SSH keys is tied to your old email. You are going to have to transfer it over to your new account

$ heroku login
Enter your Heroku credentials.
Email: incorrect@email.com
Password: 

$ heroku keys:remove incorrect@email.com

and add it to your new account

$ heroku login
Enter your Heroku credentials.
Email: correct@email.com
Password: 

$ heroku keys:add

Failing that, try recreating and add a new ssh key

Answer 2

Removing known_hosts entry for ssh should help. For linux and mac it is in the $HOME/.ssh directory

Answer 3

In my case, I simply had to switch to using ssh.

git config --global url.ssh://git@heroku.com/.insteadOf https://git.heroku.com/

If the heroku remote uses https , git seems to pull the credentials from elsewhere.
