Unrecognized PORT command

Question

In my localhost, running below command

PORT=4080 node server.js

But, it was throwing an unexpected error.

\'PORT\' is no

Answer 1

Here's a moronic way I found to recreate this problem:

1. Create a npm based app on one system
2. check it out on another system
3. FAIL to run npm install
4. run npm start

Receive error described in question.
