title: pipenv install packages for python is not working
body: <p>I am new to Python and therefore I am struggling to resolve the following problem. I installed <em>pip</em> and I made a user installation of <em>pipenv</em> and then on my project folder I run the command: </p>
  
  <pre><code>pipenv install requests
  </code></pre>
  
  <p>which gives me an error saying that the <em>pipenv command either wrong or cannot be found</em>.</p>
  
  <p>I added following path on my system environment variables the :</p>
  
  <pre><code>C:\Users\andri\AppData\Roaming\Python\Python37\Scripts
  </code></pre>
  
  <p>but still it does not work. Does anyone have an idea as to what I should do next in order to fix this? Thanks in advance</p>
  
  <p>UPDATE:</p>
  
  <p>My operating system is Windows.</p>
  
  <p>Here is how I installed pip through cmd</p>
