title: pip3 cannot be found after installing python3 and pip3 on a mac
body: <p>python2 is installed on every mac and I installed python3 and used it a lot with the standard libraries. Now I wanted to use pip3 as I did with pip and it says:</p>
  
  <p><code>-bash: pip3: command not found</code></p>
  
  <p>I downloaded <code>get-pip.py</code>found in StackOverflow's answers and with installing it I got:</p>
  
  <p><code>Requirement already up-to-date: pip in /usr/local/lib/python3.6/site-packages</code></p>
  
  <p>In addition to that I tested with <code>which pip3</code> and there was <em>no</em> output, just the new line with the normal shell. And with <code>which pip</code> there is the location output like I expected:</p>
  
  <p><code>/usr/local/bin/pip</code></p>
  
  <p>I installed python3 with the package and last month I installed <code>brew</code>. Maybe this created the conflict because I think I had use <code>pip3</code>for some libraries my installation of python3.</p>
  
  <p>(<em>What possibility do I have to use python3 without having to uninstall python2 and python3 because I need both of them and got the answer that it's no problem to install both of them?</em>)</p>
  
  <p>Thanks @phd for linking to another question. With</p>
  
  <p><code>alias pip3='python3 -m pip'</code></p>
  
  <p>in <code>~/.bash_profile</code> I can use pip3 as used.</p>
  
  <p>But I do want to know if there is still a place where pip3 is located in python3 and how I can find it?</p>
  
  <p>Thanks a lot.</p>
