title: Rails: Why is bundle install frozen up by sassc 2.4.0
body: <p>I'm trying to deploy my rails app with Capistrano, however, the deploy process (<code>cap production deploy</code>) is constantly held up at the line:</p>
  <p><code>$HOME/.rbenv/bin/rbenv exec bundle install --path /home/deploy/appname/shared/bundle --jobs 4 --without development test --deployment -- quiet</code></p>
  <p>When I ssh into the server and run the same command in the latest release without the <code>--quiet</code> flag, I see most gems are installed, but when it gets to</p>
  <p><code>Installing sassc 2.4.0 with native extensions</code></p>
  <p>it freezes. If I monitor the CPU with cloud watch (I'm using an EC2 instance running Ubuntu 20.04), I see it also spikes. I've tried removing all dependencies that rely on sassc, but this has proven a really big headache and seems like it shouldn't be necessary. Some dependent gems include my CMS (comfortable mexican sofa), webpacker, and some node dependencies.</p>
  <p>I've also tried to install sassc using</p>
  <p><code>apt-get install sassc</code></p>
  <p>to no avail (it installs, but bundle install still freezes).</p>
  <p>Does anyone have any idea why this gem is having so much trouble installing? Any workarounds/fixes? By the way, the dependencies install and run fine locally on my macOS Catalina machine.</p>
  <p>Bonus:
  Here's the CPU usage when I run the deploy script:

  <p>Maybe it's simply not possible to install sassc with the free EC2 plan?</p>
  <p>Thanks.</p>
