title: python3.7 No module named pip
body: <p>i had a problem with installing packages to new upgraded python to version 3.7</p>
  
  <p>When i type:</p>
  
  <p><code>python3.7 -m pip install pip -d</code></p>
  
  <blockquote>
    <p>/usr/local/bin/python3.7: No module named pip</p>
  </blockquote>
  
  <p>I make easy_install like this: <code>sudo easy_install pip</code> what solve previous problems, but now it create pip3.7 in a weird way. Whem i calling for pip3.8 version, this returns me a message:</p>
  
  <p><code>pip3.7 -V</code></p>
  
  <blockquote>
    <p>pip 19.2.3 from /usr/local/lib/python3.5/dist-packages/pip (python 3.5)</p>
  </blockquote>
  
  <p>Someone know what i am doing wrong? I tried many things to resolve it. Reinstall, purge, install with symbolic link from python2 etc.</p>
  
  <p>There is a script which i used to install python3.7 (i had also a problem with zlib):</p>
  
  <pre><code>sudo cd /home
  sudo wget https://www.python.org/ftp/python/3.7.3/Python-3.7.3.tar.xz
  sudo tar xf Python-3.7.3.tar.xz
  sudo cd ./Python-3.7.3/
  sudo ./configure
  sudo make
  sudo make install
  sudo update-alternatives --install /usr/bin/python3 python3 /usr/local/bin/python3 10
  python3 --version
  </code></pre>
  
  <p>Where is a mistake?</p>
