node 0.12.x const in strict mode issue

Question

I'm running node v0.12.7, and installed protractor through npm. Now I'm trying to run the conf.js using this simple tutorial, and I get the following error when executing the command protractor conf.js:

[launcher] Process exited with error code 1
C:\Users\ramtin\AppData\Roaming\npm\node_modules\protractor\node_modules\selenium-webdriver\index.js:25
const builder = require('./builder');
^^^^^
SyntaxError: Use of const in strict mode.

Can't update node due to dependency issues it will produce (I'm working on an already-built project which used node 0.12.17).

Using --harmony flag on protractor doesn't work. Do I need to install a specific version of protractor to be compatible with node 0.12.7? Or should I use babeljs to compile ES6 to ES5?

If babeljs is the answer, how would I use it for protractor?

Do I need to install a specific version of protractor to be compatible with node 0.12.7

You need protractor version 2.
