Installation problems with CodeceptJS on Ubuntu

I was setting up a new system to use CodeceptJS and got into a problem. I've followed these notes, but just get an error when I try to run the code. Mistake...

codeceptjs
/usr/local/lib/node_modules/codeceptjs-webdriverio/node_modules/codeceptjs/lib/mocha_factory.js:6
let mocha;
^^^

SyntaxError: Block-scoped declarations (let, const, function, class) not yet supported outside strict mode

    at Module._compile (module.js:409:26)
    at Object.Module._extensions..js (module.js:416:10)

      

        
        
        
      

    

My node.js and npm are installed globally via the usual apt-get and npm -g

System Information ...

• Ubuntu 17.04 x86_64
• nodejs: 4.7.2
• npm: 4.5.0
• bash 4.4.5

Does anyone know the cause of this problem or how to work around it?

Just like an update, thanks to artem for the note on 'use strict';

, I added that to the top of node_modules / codeceptjs / lib / mocha_factory.js and that I think got me going through the initial issue. However, I now see the problem in node_modules / codeceptjs / lib / output.js. Mistake...

codeceptjs
/usr/local/lib/node_modules/codeceptjs-nightmare/node_modules/codeceptjs/lib/output.js:139
function print(...msg) {
               ^^^

... I've tried several things to fix this by adjusting the print function there, but no luck so far.

This is similar to the codeceptjs-nightmare and codeceptjs-webdriverio meta packages.

I would be grateful for any ideas, suggestions or alternatives anyone has.
