title: npm install errors for package scrypt
body: <p>I need to install an npm package on my computer, which has a dependency on the package &quot;scrypt&quot;. When installing, the build fails due to this dependency. Now, im looking to resolve this error, first (obvious) idea being to install the scrypt-package separately.</p>
  <p>Some info for the environment: I am running MacOS X 10.15.6 and npm 6.14.6. My GCC is</p>
  <pre><code>Apple clang version 11.0.3 (clang-1103.0.32.62)
  Target: x86_64-apple-darwin19.6.0
  </code></pre>
  <p>Heres what happens when I try to install the package:</p>
  <pre><code>npm install -g scrypt
  
  &gt; scrypt@6.0.3 preinstall /usr/local/lib/node_modules/scrypt
  &gt; node node-scrypt-preinstall.js
  
  
  &gt; scrypt@6.0.3 install /usr/local/lib/node_modules/scrypt
  &gt; node-gyp rebuild

  <p>Now, I went and read about this in stack overflow and similar sites and thought it might be an issue due to missing permissions. Still, setting the entire node-folder in /usr/local/lib/node-modules to chmod 777 doesnt do anything - and running node using sudo simply fails.</p>
  <p>I also completely removed everything (node etc) and reinstalled from scratch (via brew) - same problem...</p>
  <p>Anyone has an idea how to solve this issue?</p>
