Error: Cannot find module 'express'

[Grunticus03]

When executing nodejs /server/app.js, I get the following error:

module.js:328
    throw err;
    ^

Ok, so I unzipped this repo to /etc/textbelt then executed npm install which then installed all the dependencies. When I run nodejs ./server/app.js I get the following error:

/etc/textbelt/server/app.js:51
  let { message } = req.body;
      ^

SyntaxError: Unexpected token {

    at startup (node.js:136:18)

So I nano app.js and change the curly braces to parenthesis and run nodejs ./server/app.js again. This time, I get the following error:

/etc/textbelt/lib/text.js:6
let config = require('./config.js');

Hello, late reply but it looks like you're using an old version of node without ES6 support.
