How to fix “Zsh: command not found – brew” on MacBook Silicon?

Homebrew installation problem

Homebrew installation problem

Homebrew can be installed on Apple silicon M1 devices but the installation script put the files into this directory 
(/opt/homebrew)
So, when you try to use any command like “brew help”
​you will get this error message        “Zsh: command not found – brew”
which means you have to move homebrew to its correct place under usr/local folder to be fixed.

To correct the installation you have to use these commands separately on terminal


​ 1) Write this command on terminal; and press return

export PATH="/opt/homebrew/bin:$PATH"


2) Then this command on terminal and press return 

​echo 'export PATH="/opt/homebrew/bin:$PATH"' >> $HOME/.zshrc

​you will see nothing after these commands and this is good.
now, write the command “brew help”

you will find that everything is ok and homebrew is working correctly 🙂
