SyntaxError: Use of const in strict mode?

I am trying to login on facebook.com with selenium-webdriver.

var webdriver = require('selenium-webdriver'),
    By = require('selenium-webdriver').By,
    until = require('selenium-webdriver').until;

var driver = new webdriver.Builder()
    .forBrowser('firefox')
    .build();

driver.get('https://www.facebook.com/login');
driver.findElement(By.id('email')).sendKeys('****');
driver.findElement(By.id('pass')).sendKeys('*****');
driver.findElement(By.id('loginbutton')).click();

driver.findElement(By.linkText('Settings')).then(function(element) {
  console.log('Yes, found the element');
}, function(error) {
  console.log('The element was not found, as expected');
});
driver.quit();

It is giving error:

/home/shubham/node_modules/selenium-webdriver/index.js:25
const builder = require('./builder');
^^^^^

node --version v0.10.37

npm --version1.4.28

protractor --version Version 3.2.2

Updating nodejs solved the issue:

npm cache clean -f
sudo npm install -g n
sudo n stable
node --version
node app.js

You have to run the second and third command as root/administrator.

n stable wouldn't do the trick for me. On the other hand,

nvm install stable

That actually got me to last nodejs version. Apparently n stable won't get pass v0.12.14 for me. I really don't know why.

Note: nvm is Node Version Manager, you can install it from its github page. Thanks @isaiah for noting that nvm is not a known command.

For me it was more simple to solve, just going to the Node web site, get and install the LTS version.

Update your node and it will resolve this problem.
