I was settings up a new system to use CodeceptJS and have hit an issue. I followed these notes, but just get an error when trying to run codeceptjs. The error is...

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

My node.js and npm is installed globally via normal apt-get and npm -g

System info...

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

Does anyone know the cause of this issue or how to get around it?

Just as 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 past the initial problem. However I now seem to be hitting an issue in node_modules/codeceptjs/lib/output.js. The error is...

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

...I've tried a few things to resolve this, adjusting the print function there, but with no luck yet.

This seems to be the same with the codeceptjs-nightmare and codeceptjs-webdriverio meta-packages.

I'd be grateful of any ideas, suggestions or alternatives anyone has.
