brew installation for zsh?

This worked for me:

export PATH="/usr/local/bin:$PATH" >> ~/.zshrc

This worked for me on macOS ARM (Apple M1):

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

and then:

export PATH="/opt/homebrew/bin:$PATH" >> ~/.zshrc

Not sure if this is late but you can simply run this to add Homebrew to your PATH:

eval $(/home/linuxbrew/.linuxbrew/bin/brew shellenv)

Try setting this line in your .zshrc

export PATH=/usr/local/bin:$PATH
