Your question is a bit weird, but in Meteor app you need to add meteor before your npm command.

For example:
meteor npm i

Hi storyteller
I don’t understand it. I downloaded node.js from the official site, installed it, and clicking on it, I’ve got cli, wher I typed npm and it was not recognized. what did I do wrong? this testing matter with mocha is difficult, not having proper documentation or relevant support is not possible to learn and use it. still I don’t get it. is there any help? thank you frank

Are you trying to use mocha with a Meteor app, or is this for a standalone Node app?

to be honest I am very confused. I downloaded node.js and installed it. clicking on it a cli opened up and tried to follow instructions from node.js site, I’ve got error message.
another option was: sitepoint: I copied and pasted links in my html page, then initializing mocha , not working. I try to test jquery code of form fields and I screwed up. can I get help? thank you , frank
ps : if I use meteor , what shoul I do to be able to use mocha? thank you, frank

I tried standalone node app

If I remember correctly you will have to install npm for that before you can proceed. Can’t really help you there as I haven’t build a node only app in ages so I don’t recall what the process there is.
