title: zsh: /usr/local/bin/pipenv: bad interpreter: /usr/local/opt/python/bin/python3.7: no such file or directory
body: <p>I recently switched from bash to zsh (MacOS). I haven't used pipenv since the switch. Now when I run any pipenv command I get the following error:</p>
  <pre class="lang-sh prettyprint-override"><code>$ pipenv install
  zsh: /usr/local/bin/pipenv: bad interpreter: /usr/local/opt/python/bin/python3.7: no such file or directory
  </code></pre>
  <p>I use pyenv for Python dependency management:</p>
  <pre class="lang-sh prettyprint-override"><code>$ which python
  /Users/ryan.payne/.pyenv/shims/python
  </code></pre>
  <p>My default python version is 3.7.3:</p>
  <pre><code>$ pyenv versions
    system
    2.7.16
    3.6.8
  * 3.7.3 (set by /Users/ryan.payne/.pyenv/version)
  </code></pre>
  <p>It seems like pipenv is not using my pyenv version of Python. How do I get pipenv working again?</p>
