SyntaxError: Use of const in strict mode?

Question

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');
^^^^^

Answer 1

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.

Answer 2

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.

Answer 3

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