title: How to solve the "pip install pygame" issue?
body: <p>I am trying to use command <code>pip install pygame</code> in cmd, but there is error.
  The error is shown as follows:</p>
  
  <pre><code>C:\Users\Administrator&gt;pip install pygame
  Collecting pygame

  Could not install packages due to an EnvironmentError: [WinError 5] 拒绝访问。: 'c:\\program files (x86)\\python37-32\\Lib\\site-packages\\pygame'
  Consider using the `--user` option or check the permissions.
  
  You are using pip version 18.1, however version 19.1.1 is available.
  You should consider upgrading via the 'python -m pip install --upgrade pip' command.
  </code></pre>
  
  <p>I follow the instruction in the error but still cannot solve the problem. And I also found whatever "pip" command cannot be installed correctly.</p>
