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

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

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.
I installed firebase tools using
sudo npm install -g firebase-tools
and everything seemed to install fine. I already had npm and node.js installed and these are the versions:
npm: 2.11.3
node: v0.12.7
But when I try running
firebase init
from my project file, I get this error
/usr/local/lib/node_modules/firebase-tools/node_modules/request/node_modules/hawk/node_modules/boom/lib/index.js:5

How can I fix this error?
This error is due to Node.js version, you need to update to version 8 or higher.
