Error while installing angular-cli globally through cmd

I have been trying to install Angular CLI on my Windows system.

I am new to this, and have been following steps given in https://angular-templates.io/tutorials/about/learn-angular-from-scratch-step-by-step to setup my environment. Since I am using Windows, I used "nodist" NVM method to install node and npm on my system. I can successfully run both these commands hinting to the fact that perhaps npm and node have been installed correctly -

C:\WINDOWS\system32>npm -v
1.2.24
C:\WINDOWS\system32>node -v
v0.10.9

Now, to install Angular CLI, I ran -

C:\WINDOWS\system32>npm install -g @angular/cli
npm ERR! addLocal Could not install angular/cli
npm ERR! Error: ENOENT, stat 'C:\WINDOWS\system32\angular\cli'
npm ERR! If you need help, you may report this log at:

I tried creating a folder 'C:\WINDOWS\system32\angular\cli'. Also, tried cleaning cache and retrying. But none of it helped.

Edit :

Okay I tried setting up through the installer file mentioned in one of the comments, and now I have node version - "10.16.3" and npm version - "6.9.0". But running the mentioned command for installing angular-cli gives me this error :

C:\WINDOWS\system32>npm i -g @angular/cli
npm ERR! code ECONNREFUSED
npm ERR! errno ECONNREFUSED
npm ERR! FetchError: request to http://registry.npmjs.org/@angular%2fcli failed, reason: connect ECONNREFUSED 104.16.18.35:80

Also, I am using a system at my office. And looking up the proxy settings at "Change Proxy Settings" on Windows, I don't see any Proxy server being used.

Solution

It looks like you have the wrong node version or the overall installation file. You can get the working version of node here https://nodejs.org/en/ and choose the recommended version for most users. go through the installation process and after that just run npm i -g @angular/cli.
