Yeoman fails to run - node.js

I'm on centos 7 and I just installed nodejs version 6.14.3, npm version 3.10.10, and yo version 2.0.5. I then ran the command
yo code
In an attempt to use the yeoman generator to create a vscode extension. I then got the following error:
/usr/lib/node_modules/generator-code/generators/app/index.js:47
async prompting() {

Not sure if I'm just missing a silly dependency or something. Any ideas?

This node version, 6.X, doesn't support asyncs.
Definitely install a newer version, I recommend at least 8.X to not to risk other incompatibilities at the language level.

Any help to fix this will be highly appreciated.

The error is showing that node doesn't understand the ... spread syntax.
You should upgrade node to a version that has full support for spread (8.3+).
If possible, you should use the LTS (long-term support) version of node (currently 14.16.1).

This error was caused due to installing an old version of Node.JS on your OS.
You can try updating to the LTS version. To find out what version your running you can run the command
node -v
Good Luck!

Vue CLI requires Node.js version 8.9 or above (8.11.0+ recommended).
You should update your nodejs version

what could be wrong
It's seem your nodejs version does not support ES2015, update your node to version 6+
you can using nvm to manage your node version
Your need Node version 6.x or higher
See documentation below
take a look here: https://github.com/angular/angular-cli/issues/4604
