Nodemailer Error Can't Fix

Question

I have a very simple application, just starting to get my hands dirty with nodemailer. When I run the app I get errors in the module itself.

app.js:

const nodemailer = require('nodemailer');

const transporter = nodemailer.createTransport('smtps://me%40gmail.com:supersecretpw@smtp.gmail.com');


var mailOptions = {
    from:    '"Me" <me@gmail.com>', // sender address
    to:      'him@him.com, her@her.com', // list of receivers
    subject: 'Hello dude', // Subject line
    text:    'Test email with text', // plaintext body
    html:    "Testing 1..2..7" // html body
};

// send mail with defined transport object
transporter.sendMail(mailOptions, function (error, info) {
    if (error) {
        return console.log(error);
    }
    console.log('Message sent: ' + info.response);
});

And I get this error:

C:\Users\Andrew\desktop\messy4\node_modules\nodemailer\lib\mailer\index.js:31
            compile: [(...args) => this._convertDataImages(...args)],
                       ^^^

Really not sure what's happenning here.

Answer 1

Node.js version 6+ is required. Check your Node version with the following command:

node --version

If you are not at least 6+ then you must upgrade.

You may receive another error message instructing you to login to your account. In that case, go to your email inbox and you will see a message from Google with a link to a page for setting up less secure app permissions.

Answer 2

Simply Add this in your package.json file.

"engines": {
    "node": "6.9.4"    // You can use any version
  }

This will automatically download the node version you provide. By this way you don't need to upgrade your NodeJS every time in server.

Answer 3

Nodemailer is compatible with Node version 6 or above (as per https://nodemailer.com/about/#requirements)

So follow these steps to upgrade node:

1* sudo npm cache clean -f

2* sudo npm install -g n

3* sudo n stable

4* sudo ln -sf /usr/local/n/versions/node/5.4.1/bin/node /usr/bin/node (the bold text/version should be the one installed in during above step.)

ie if 8.1.1 is installed then do sudo ln -sf /usr/local/n/versions/node/8.1.1/bin/node /usr/bin/node

node –v (Should show updated version now)
