Use NVM to handle Angular-Node.js incompatibility (e.g., Uncaught SyntaxError: Unexpected token 'export')

I wanted to setup MySQL to use utf-8 on the MAMP installation on my Mac. I tried the instructions from this article: http://cameronyule.com/2008/07/configuring-mysql-to-use-utf-8/ However, I kept getting error messages that are similar to this one [ERROR] /Applications/MAMP/Library/bin/mysqld: unknown variable 'default-collation=utf8_general_ci' I did some search and realized that several variables are deprecated.
