title: How to import requirements.txt from an existing project using Poetry
body: <p>I am trying out <a href="https://python-poetry.org/" rel="nofollow noreferrer">Poetry</a> in an existing project. It used pyenv and virtual env originally so I have a <code>requirements.txt</code> file with the project's dependencies.</p>
  <p>I want to import the <code>requirements.txt</code> file using <strong>Poetry</strong>, so that I can load the dependencies for the first time. I've looked through poetry's documentation, but I haven't found a way to do this. Could you help me?</p>
  <p>I know that I can add all packages manually, but I was hoping for a more automated process, because there are a lot of packages...</p>
