SyntaxError: Use of const in strict mode

I have updated node and npm, but every time running, getting the error below. System is Ubuntu Server 14.04.

rolle@ghost:~$ vtop

/usr/local/lib/node_modules/vtop/app.js:3
const App = ((() => {

What version of nodejs? You may need to run it via node directly with the --harmony flag.

I have v10.16.3. But I've tried different versions from 7 and up, everything outputs this same error. I have no idea how to run directly with --harmony, haven't used it before.

This is also strange because vtop works on other similar 14.04 server I have... humm.

Same issue here.

Ended up having to call node with the path to the app.js. With nvm and my version of Node, this ended up being:

node ~/.nvm/versions/node/v8.9.4/lib/node_modules/vtop/app.js
