ERROR: Please install mysql2 package manually

So I finally figured out the bug. The issue appears to come from when you are calling the migration from global install of sequelize-cli instead of the locally installed version of sequelize in my project. All I had to do was call the script form the node modules folder and it worked perfectly. I was calling the command this way sequelize db:migrate when I needed to call the local installed package this way node_modules/.bin/sequelize db:migrate

i installed mysql2 package globally out of my project folder using :

npm install mysql2 -g

1. List your global npm packages

   npm list -g --depth 0

2. Uninstall sequelize

   npm uninstall -g sequelize

3. Install sequelize in project scope

   npm install --save sequelize

This one worked for me

npm install mysql2 --save
