title: Why can't I update pipenv to latest version?
body: <p>If I check my version of pipenv it always shows 5.3.5, but I know there is newer version 11.0.2. How can I update it using pip?</p>
  
  <pre><code>C:\hello_world&gt;pip search pipenv

  <p>The question is very simple, but mostly code to show you guy what I'm seeing. So this is basically filler text so that StackOverflow stops flagging that the question is mostly code. Please help.</p>
