  <p>I installed pyenv and pyenv-virtualenv using Homebrew, and the update and doctor add-ons by cloning the GitHub repository. The command <code>brew list</code> gives the following output:</p>
  <pre><code>fig             pyenv-virtualenv    xz
  openssl@1.1     pyenv               readline
  </code></pre>
  <p>My .zshrc file looks like this:</p>
  <pre><code>if command -v pyenv 1&gt;/dev/null 2&gt;&amp;1; then
    eval &quot;$(pyenv init -)&quot;
  fi
  </code></pre>
  <p>and .zshenv file like this:</p>
  <pre><code>eval &quot;$(pyenv virtualenv-init -)&quot;
  </code></pre>
  <p>I'm not sure what other information is relevant, so you can ask for more in the comments.</p>
