Syntax error near babel-polyfill

[thijssmudde]

I'm using node v12.4.0 and running bash mup init gives the following error. This is right after mup-node is installed globally with npm

/Users/user/.nvm/versions/node/v12.4.0/bin/mup: mup: line 2: syntax error near unexpected token'babel-polyfill''
/Users/user/.nvm/versions/node/v12.4.0/bin/mup: mup: line 2: require('babel-polyfill');'
