Q:

Quick Start (not so quick)

Based on the Quick Start guide for CxJS, the following commands:
md my-app
cd my-app
npm init -y
npm install cx-cli --global
cx scaffold
npm start
result in:

My node version is 6.11.3 and npm is 3.10.10, which I believe should be recent enough.  Can anyone lend some insight.  I'm attempting to evaluate CxJS as a replacement for ExtJS, but as of right now, I'm stuck. 

A:

Error: listen EACCES 127.0.0.1:8088 
Implies that the process was not able to claim that port.  Check that something is not already running on port 8088
