  Can't run custom module on AWS/nodejs. Exits with error: Cannot find module
  
  I want to switch to a fork of the parse-server module on AWS elastic beanstalk, but no matter what I try I get this error when the server tries to start up:
  Error: Cannot find module 'parse-server'

  The original module works without a problem:
  
  in package.json:
  
  "parse-server": "3.10.0",
  
  but neither of these ones do work:
  
  "parse-server": "https://github.com/andrewking0207/parse-server.git#appleAuth",
  
  "parse-server": "andrewking0207/parse-server.git#appleAuth",
  
  when I ssh into to the ec2 instance the module is installed inside node-modules.
  What am I missing here?? Locally on my machine everything runs fine.
  
  A:
  
  You can not install directly from a GitHub fork because it does not have the lib folder which is created during the build process. There is a workaround though:
  1 - Clone your fork to your machine
  2 - Remove the lib folder from the .gitignore file
  3 - Run npm install
  4 - Run npm build
  5 - Commit the changes to your local git
  6 - Push the commit to your remote fort branch at GitHub
  Then you can try to install it again and it should work. I just wanted to make clear that it is a workaround and not the recommended way to use Parse Server. If you explain what you want to achieve by using your own fork, I can try to advice about the "right" way to be done.
