I'm trying to install the polymer CLI from here: https://www.polymer-project.org/1.0/docs/tools/polymer-cli
However, after installing it I get an error when trying to run polymer help:

My node version is v0.10.26, my nodeenv version is 0.3.3. I'm using Mac.
Does anyone know how I would fix this?
Polymer CLI is not compatible with Node v0.10.26.
The setup guide indicates that Node 4.x or newer is required. You should actually upgrade to the latest stable version (6.2.0).

Any way to fix this?
As per my knowledge
Async Await is not available in node v6.5.0,
which you are using. So you can upgrade your node version or can start using Promise object with the same version of node.
In my case, npm list chokidar helped me realize it was another module (gulp-nodemon) that used a newer version of chokidar. It worked after downgrading it.
I had exactly the same error...! it was a node version problem, I was on node version 6, this is what I did to fix it:
nvm install <VERSION_NUMBER> // nvm install 10.15.3
nvm use <VERSION_NUMBER> // nvm use 10.15.3
node -v // confirm i am using the correct version of node
Remember to do this on your computer not just your code file and change the default node version with nvm alias default 10.15.3
you can check your default lists with
nvm list

I am using Express.js framework. It was working fine last time when i worked on it.
After searching a lot i finally found that for one of my project which was build with nodejs older version i was using node#4.4.7 and after changing node version on my local machine with following:
nvm ls // to check out what versions of Node.js are installed on your machine
-> v4.4.7
v8.9.1
system
default -> 4.4.7 (-> v4.4.7)
To switch Node.js from node#4.4.7 to node#8.9.1 i have used following command:
nvm use v8.9.1
To verify i check again with nvm ls and now it shows.
v4.4.7
-> v8.9.1
system
default -> 4.4.7 (-> v4.4.7)
Yes the spread operator which is available in ES6 will be available form versions 8 and above for node 8 .

I don't have any idea how to proceed. I have searched the internet to my capabilities and still unable to find a solution.
I have tried installing using "npm install -g heroku-cli" but still getting the same error.
Any help will be appreciated.
Thanks!
heroku-cli requires a minimum node version of 6.15.24. Upgrade your node. The latest stable version of node is 8.9.4

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?

You need protractor version 2.
