title: NPM pulls corrupted packages from Verdaccio instance
body: <p>When I perform a basic <code>npm install</code> in an application I am attempting to set up a dev. environment for corrupted packages end up being pulled from my Verdaccio proxy instance.</p>
  
  <p><strong>To Reproduce</strong></p>
  
  <p>Steps to reproduce the behavior:</p>
  
  <ol>
  <li>Set up package.json for my project including adding my dependencies,
  etc. </li>
  <li>Set my local system to use my Verdaccio instance: <code>npm set
  registry [[Verdaccio Server URL]]:4873</code>.</li>
  <li>Perform <code>npm install</code> within the directory I have the package.json in.</li>
  </ol>
  
  <p><strong>Results</strong></p>
  
  <p>I get a ton of output similar to the following:</p>
  
  <pre><code>npm http fetch GET 200 [[Proxy NPM Site]]/@angular%2fplatform-browser-dynamic/-/platform-browser-dynamic-5.2.11.tgz 6430ms
  npm WARN tarball tarball data for @angular/router@5.2.11 (sha512-NT8xYl7Vr3qPygisek3PlXqNROEjg48GXOEsDEc7c8lDBo3EB9Tf328fWJD0GbLtXZNhmmNNxwIe+qqPFFhFAA==) seems to be corrupted. Trying one more time.
  npm WARN tarball tarball data for jquery@3.3.1 (sha512-Ubldcmxp5np52/ENotGxlLe6aGMvmF4R8S6tZjsP6Knsaxd/xp3Zrh50cG93lR6nPXyUFwzN3ZSOQI0wRJNdGg==) seems to be corrupted. Trying one more time.
  npm WARN tarball tarball data for ng-bootstrap@1.6.3 (sha1-1B/UIVTAWTQiy4PEc6OCiqdSW/U=) seems to be corrupted. Trying one more time.
  </code></pre>
  
  <p>Note the URL encoded name of the package, in this case <code>@angular%2fplatform-browser-dynamic</code>. I do not get this when I set my proxy to be <code>https://registry.npmjs.org/</code>.</p>
  
  <p>Of course, what I would like to do is be able to perform an <code>npm install</code> just as if I were connected to the official registry.</p>
