Error: npm install -g @angular/cli

Question

When I am trying to run this command, it through error and NPM does not install completely.

Before this version of Node.js I also installed node-v8.9.1-x64.msi, but their same issue I was facing that's why I uninstalled and installed node-v6.11.0-x64

But still, I am not able to solve this issue.

Node Version: v6.11.0 NPM Version: 3.10.0

I think sudo is linux command...I am trying to install this in Window 7 OS. — Vinit ..., Nov 24 '17 at 08:46
It could be caused by Windows Defender Real Time Protection. I struggle with this error constantly. There is probably a way to set specific exclusions, but I haven't been able to figure it out. I have to temporarily disable real time protection (and cloud-delivered protection) any time I want to install/upgrade the CLI, or even create a new project. It's such a pain, and the only thing keeping me from promoting the CLI to my team. — David, Jan 24 '18 at 20:35

Normally I'd say "use it with sudo" like

sudo npm install -g @angular/cli

But since you are on Windows, try with an elevated command prompt.
In other words: Start your console (CMD) as Administrator and run the command again.

If that doesn't work, type

npm cache clean

And then just run

npm install -g @angular/cli

again.

For Angular 4+ project development, you should use latest node version v8.8.9. So that you won't face any errors related to any modules.

I have same issue while trying to install @angular/cli

I found the node.js version I had installed was 6.10. Then I upgraded my node.js to 8.10.0 and tried:

npm install -g @angular/cli works fine.

The old version of npm doesn't support new features of Angular.
