Problem: angular-gh-pages bash: /dev/tty: No such device or address
Help for git remote remove: https://help.github.com/articles/changing-a-remote-s-url/
fatal: could not read Username for ‘https://github.com’: Invalid argument #71
For me the solution to this was updating the remote URL to:
git remote set-url origin https:// <-- replace with your custom details / creds.
Hoping this will work!
git config --global credential.helper wincred
