title: ZSH: Command not found - after update macOS to 10.15.1
body: <p>Yesterday I was using all my installed packages without any problem such as <code>mysql</code>, <code>composer</code>, <code>php</code>, <code>brew</code> and co...</p>
  
  <p>However, today I started my MacBook and typed <code>mysql</code> and I got: <code>zsh: command not found: mysql</code>. Not even <code>brew</code> is working anymore and I don't know why.. this is my <code>.zshrc</code> config file and I don't know why it isn't working.</p>
  
  <pre><code># If you come from bash you might have to change your $PATH.
  export PATH=$HOME/bin:/usr/local/bin:~/.composer/vendor/bin:$PATH
  </code></pre>
  
  <p>Any ideas how to fix this?</p>
