Ionic start command throws error -- process.on('unhandledRejection', r => console.error(r));


Hello I am trying to create a new sideMenu ionic project using the ionic start command from the cmd.

However when I type:

ionic start test-app sideMenu --v2

I get the following error:

process.on(‘unhandledRejection’, r => console.error®);

SyntaxError: Unexpected token =>

This person had the same issue:

I have tried deleting Cordova and Ionic from the File Explorer and reinstalling. Also I made sure that I had the latest version of npm and node js installed. Still no luck.

Any help with this problem would be great. Thank you!


This is not the current format of the ionic start command:

What is ionic info output?
Are you using a recent release?


I get the same error when I type the ionic info command! What do you suggest to eliminate this issue?


npm uninstall -g ionic and then npm install -g ionic again - something is broken with your installation.


Hi, I had the same problem and it was due to nodeJS not being up to date. I fixed it by upgrading node.
