npm install jquery error / saveError ENOENT / Invalid dependency

Question

I'm having trouble to resolve this issue. I've searched around but not getting anywhere. I've just started learning MEAN Stack. I'm trying to install all components for the Stack. (I currently have programs installed for Python Stack and Ruby Stack). Not sure if those will have anything to do with my problem. I'm still new to programming. Any info would be greatly appreciated.

Here is what I'm running currently:

• MacOS Sierra v10.12.5
• Node v8.0.0
• npm v5.0.0

I've installed:

$ npm install nodemon

(-g)..global was giving me a problem so I installed without it.

$ npm install bower

(-g)..global was also giving me a problem so I installed without it.

Then when I tried to install:

$ npm install jquery

I was getting errors. Here is what it says..

Thank you for taking the time to look at this.

I had the same problem and after many errors it finally works. I deleted the files I had and restarted with these steps in the order stated:

Go to the directory you want to work in and create a folder named "node" for example

$ cd /directory/

$ mkdir node

You will need package.json so:

$ npm init

Then download express which creates node_modules where the download of jquery goes into

$ npm install express

Then install jQuery with a capital instead of without, i then tried without a capital after

$ npm install jQuery

Then npm install all other needed packages and

$ npm update

Hope this works for you :)
