I restarted my MacBook and now it won’t work

I put homebrew on my MacBook from mid 2007 because I needed to use this. It didn’t work ay all then either because it didn’t detect my bin file. I got tired, fell asleep, woke up, then tried again. Now it’s saying no command found and if I try to install it again it just says no formula found. I’ve tried this 25 times and it still won’t work.
