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

Question

Подключаю библиотеку puppeteer, в meteor приложении.

const puppeteer = require('puppeteer');

Появляются ошибки в консоли

packages/modules.js:22730                     
let asyncawait = true;
^^^

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

Версия node js v8.12.0 Версия meteor 1.4.3.2

Из-за чего это может быть и как это поправить?

---

Если вставить строку с кодом

const puppeteer = require('puppeteer');

В файле meteor приложения то генерируются такие ошибки:

packages/modules.js:22730 let asyncawait = true; ^^^
