title: npm install fail with some package not found on some server
body: <p>I am on different servers and run <code>npm install</code></p>
  
  <p>One server is ok. Another failed showing below error: </p>
  
  <blockquote>
    <p>no matching version found for es-abstract@1.14.0</p>
  </blockquote>
  
  <p>I tried <code>npm ci</code>. Same deal. </p>
  
  <p>Then I did <code>npm install es-abstract-1.14.0.tgz</code></p>
  
  <p>But the size node_modules/ are different. I am using <code>du -shc --apparent-size node_modules/</code> to ignore the <code>sparse</code> files within the folder. Why?</p>
  
  <p>Could I accept that this is the network issue of the failed server？ And just keep doing this? I mean, is the installation still going to be ok in this way?</p>
