How to fix command not found brew on mac with zsh

I got a new MacBook Pro with M2 chip last week. As a web programmer, I needed to install php on macOS. Followed by the php.net provided install instruction, I installed php on macOS with homebrew.

After installing homebrew, I used the command “brew install php”, but got an error message: “zsh: command not found: brew”.

Here is the solution that I fix this problem.

Place brew in zshrc $PATH:

echo “export PATH=/opt/homebrew/bin:$PATH” >> ~/.zshrc

Then, repair brew:

brew doctor

The Terminal still shows the error message.

I try manually adding the following line to the .zshrc file:

eval $(/opt/homebrew/bin/brew shellenv)

Or add this to the zshrc with a single command:

echo “eval $(/opt/homebrew/bin/brew shellenv)” >> ~/.zshrc

Then, run “brew doctor” again.

The Terminal prompts: “Your system is ready to brew”.

Finally, I can install php by “brew install php”.
