title: Copy installed packages using pip to another environment
body: <p>I downloaded some packages in my environment using pip command. And I want to have a copy of them to transfer them to another environment. I know that using:</p>
  
  <pre><code>pip freeze &gt; requirements.txt
  </code></pre>
  
  <p>will generate requirements into a file, but since my second environment does not have access to internet i can not use:</p>
  
  <pre><code>pip install -r requirements.txt
  </code></pre>
  
  <p>to install that packages again.
  Is there any way to copy installed packages? or somehow install packages in a specified directory in my first environment?
  Thanks</p>
