If you have separate dev/staging and production servers, ensure you copy/commit both your composer.json and composer.lock files to production and always run composer install --no-dev on production, rather than update. (The --no-dev switch will stop any packages listed in 'require-dev' from being installed, typically modules for debugging and libraries for unit/behavioral testing.)

1. go to WHM, find MultiPHP INI Editor, find php 7.2, ensure allow_url_fopen is Enabled
2. increase ram
3. download composer
https://getcomposer.org/download/
4. Run locally php composer.phar require drush/drush:8.x
5. upload the composer.json and composer.lock files
5. Run remotely php composer.phar install
6. Run remotely ../vendor/drush/drush/drush status, cr, ups, up drupal
7. Run updates.php

/**

Following Steps will make working with External JavaScript libraries in Drupal 8 absolutely clear (including how to conditionally load it in specific pages):

Step 1: Place the JavaScript file in your theme or module inside a folder called js. After this step your folder structure must look like :

my-theme/js/my-script.js
Step 2: If your theme already has a my-theme.libraries.yml file open it, if not create it.

In Drupal 8 Libraries are simply collections of CSS or JS files bundled together under a uniquely identified library name.
