Use Heroku binary instead of gem

Question

I have installed ruby 2.2.2 through RVM, and have also installed Heroku. I installed Heroku by downloading the most recent release from Github, installing the needed gems, and then symlinking it into /usr/bin/ so that it could be found when I needed to use the command. It worked initially, but after a while (this may have happened on restart), any heroku commands now have a ruby error.

The symlinked binary still works correctly if I explicitly specify a path.

Output:

user@BEN-PC-LINUX:~$ heroku login

Enter your Heroku credentials.

The only place that the heroku command actually works as supposed to is in /usr/local/heroku, I'm guessing because /usr/local/heroku/bin/ is searched before using the path. Even in /usr/bin/, the error occurs.

The Heroku toolbelt has an install script, running wget -qO- https://toolbelt.heroku.com/install-ubuntu.sh | sh might be a better way to install it. — frostmatthew

@Exupery I tried that, but I don't want to install the heroku package itself (which is what that does) because it installs the system ruby packages as dependencies, which I would like to avoid. — Pip

You can create a alias for heroku command put below code in .bash_profile file alias heroku="/usr/bin/heroku" — Anant Kolvankar

You can create a alias for heroku command put below code in .bash_profile file

alias heroku="/usr/bin/heroku"

.bash_profile so that it's loaded each time you open a terminal.

note:- You will have to reload your current terminal to have it working simply use

$. .bash_profile
