title: homebrew with M1 macbook air error when starting terminals
body: <p>I installed homebrew 3.0.0 on my M1 MBA.</p>
  <p>However, every session including iterm2 terminal and tmux shows this error message:</p>
  <p><code>/Users/jinrae/.zprofile:1: no such file or directory: opt/homebrew/bin/brew</code></p>
  <p>In my case, it does not harm functionality at least in my usage pattern.</p>
  <p>Anyhow, how can I get rid of this message?</p>
