Npm install not working in windows after node upgrade

Last night I have upgraded my Node.JS and after that my npm install stopped working. I have uninstall Node and reinstalled it again but that is of no use. I am using Windows 8.1, Node - 8.9.4 and NPM - 3.3.12. Below is the error I am getting while running npm install.

Your NPM is probably out of date. Try typing npm install -g npm to upgrade it, then close your command prompt and open another one, and try to do the npm install again. If that doesn't work, run node --version and npm --version and post the results in a comment here.

npm install: install Couldn't read dependencies

I have started to learn Angular JS. I am going through this, that is building simple phonecat app
I am following the steps. Node.js downloaded.

Execute this cd myproject and then execute this: npm install
Its solved. Thanks.

It looks like you haven't put the package.json file in root directory.
If you are starting fresh, you'll need to clone this repo. https://github.com/angular/angular-phonecat

Like Bilhan A said: you need to change to the folder where you cloned the project to.
From your question I am assuming you are new to programming and want to learn Angularjs primarily. Node.js is not needed for this. If you really want to learn Angular, I recommend Tutorials like this one, which do not require node.js. When you understood how it works, come back to node.js and combine them.

name field in package.json should be the same with name of your project directory.

If this is the error displayed then simply update the npm,i face this issue now that's why i update here,it might be help some one

Yeoman Javascript error involving 'mkdir'

I'm setting up a Meanjs instance with a Yeoman generator. When I do 'sudo yo meanjs' everything works fine until it looks like it is trying to make a directory and it fails, any ideas on what is going on here?

That is a pretty common error.
Yeoman is running the following:
bower install & npm install
Bower install succeeded, however NPM install is failing because of user permissions. Just run:
sudo npm install

The ZenCoder's answer is spot on, but if you want to permanently fix this permissions error, you can follow the tutorial at: https://docs.npmjs.com/getting-started/fixing-npm-permissions
Since you're on a Mac, you could actually avoid npm permissions errors altogether by just installing node instead via homebrew:
brew install node (this will install npm too)
Homebrew installs programs to a directory that doesn't require sudo for write, so you can npm install -g <whatever> freely without it.

D3.js with Total.js/node.js

I have been trying to use total.js with D3 to create a tree visualization. I am unable to download D3. I do :
npm install D3
I get:
npm ERR! contextify#0.1.8 install: `node-gyp rebuild`
npm ERR! Exit status 1

I have tried to download contextify, but I get the same thing. I have successfully downloaded gyp, but it doesn't seem work if I try to download D3.js.

Try to download latest version of node.js (with node.js v0.12.0 everything works).

Update npm and use lowercase d3
Update npm:
npm install -g npm may require sudo
Install d3:
npm install d3
Note: this will install d3 in your current location to install globally use :
sudo npm install d3 -g
