body: <p>Earlier when I poetry installed my local package its correct path used to be shown when I pip list</p>
  <p>Old versions
  poetry: 1.0.2</p>
  <p>pip list</p>
  <pre class="lang-sh prettyprint-override"><code>package                          version                        location
  ----------                       ---------                      ------------
  local_pacage                      1.0.0                         /Users/username/project
  </code></pre>
  <p>Updated version
  poetry: 1.1.6
  pip version was also updated don't remember the old version</p>
  <p>pip list</p>
  <pre class="lang-sh prettyprint-override"><code>package                              version

  <p>pip list -v shows the location as site packages always even when installed from other path using poetry.
  Earlier it used to show correctly.
  Note: Installer column shows installer as poetry, it's just the location</p>
  <pre class="lang-sh prettyprint-override"><code>package                              version              location                                                          Installer
  ----------                          ---------             ----------                                                     ------------
  local_pacage                       1.0.0                   /Users/username/site-packges                    poetry
  </code></pre>
  <p>Any idea what could be the reason. Could it be a change in poetry or pip.</p>
