title: I tried to install ionic but it returns : npm ERR! code E418
body: <p>I have a serious problem. I tried to install ionic, cordova, angular, react-native-cli, https-status-error and other packages and it always returns:</p>
  
  <pre><code>npm ERR! code E418
  npm ERR! 418 I'm a teapot: ionic @ latest
  </code></pre>
  
  <p>Please note that it may be wrong and I do not understand what is happening. It was fine until 3 days ago.</p>
