title: VSCode doesn't show poetry virtualenvs in select interpreter option
body: <p>I need help. VSCode will NEVER find poetry virtualenv interpreter no matter what I try. </p>
  
  <p>Installed poetry Python package manager using a standard <code>$ curl</code> method as explained <a href="https://python-poetry.org/docs/#installation" rel="noreferrer">in the official documentation</a>. </p>
  
  <p>Started a project by <code>$ poetry new finance-essentials_37-64</code>, installed poetry environment with <code>$ poetry install</code>. </p>
  
  <p>So now I can see that I indeed have a virtual environment by:</p>
  
  <pre><code>Jaepil@Jaepil-PC MINGW64 /e/VSCodeProjects/finance_essentials_37-64 $ poetry env list 
  &gt;&gt; finance-essentials-37-64-SCQrHB_N-py3.7 (Activated)
  </code></pre>
  
  <p>and this virtualenv is installed at: <code>C:\Users\Jaepil\AppData\Local\pypoetry\Cache\virtualenvs</code>, which has <code>finance-essentials-37-64-SCQrHB_N-py3.7</code> directory. </p>
  
  <p>However, VSCode is unable to find this virtualenv in its 'select interpreter' command. I only see a bunch of Anaconda and Pipenv environments but not the poetry environment's interpreter that I've just made. </p>
  
  <p>I also added <code>"python.venvPath": "~/.cache/pypoetry/virtualenvs",</code> to my <code>settings.json</code> as suggested in <a href="https://github.com/microsoft/vscode-python/issues/8372#issuecomment-556984062" rel="noreferrer">here</a>, but to no avail. 
  Still doesn't work. </p>
  
  <p>I also tried an absolute path, by adding <code>"python.venvPath": "C:\\Users\\Jaepil\\AppData\\Local\\pypoetry\\Cache\\virtualenvs",</code> to the same settings, but it also doesn't work. </p>
  
  <p><a href="https://code.visualstudio.com/docs/python/settings-reference" rel="noreferrer">VSCode settings reference</a> states that it has <code>python.poetryPath</code> as a default but it doesn't seem to work either. Should I change the default value <code>"poetry"</code> in this case? </p>
  
  <blockquote>
    <p>python.poetryPath </p>
    
    <p>"poetry"</p>
    
    <p>Specifies the location of the Poetry dependency manager executable, if
    installed. The default value "poetry" assumes the executable is in the
    current path. The Python extension uses this setting to install
    packages when Poetry is available and there's a poetry.lock file in
    the workspace folder.</p>

  <p>I'm on Windows 10 pro 64bit &amp; Has Python 3.7.6 installed on the system. </p>
