Warning: No available formula with the name "exercism".

Hello everyone look I have a problem when I try to install Exercism with Homebrew Formulae, I installed Homebrew and tried to install Exercism but the terminal shows me this problem, I really appreciate if anyone can help me, thanks.

That’s really odd.

Here’s what I get:

$ brew search exercism
==> Formulae
exercism ✔

What does brew config output for you?
