安装angular / cli时发生奇怪的错误

Question

I am creating an angular development environment in window 8.1 platforms. this machine has node 0.10.36 and npm version is 1.4.8

while installing angular/cli, I am getting this error

C:\Users\Admin>npm install -g @angular/cli
npm WARN `git config --get remote.origin.url` returned wrong result (git://githu
b.com/angular/cli)

I thought maybe I should uninstall node and npm and install it again so for that I have deleted npm folder by going n there "C:\\Users\\Admin\\AppData\\Roaming" but still when I type npm --v, I am getting 1.4.28

Try to follow below steps

1. Uninstall from Programs & Features from control panel.

2. Reboot (or you probably can get away with killing all node-related processes from Task Manager).

3. Look for these folders and remove them (and their contents) if any still exist. These paths are dependent upon your OS and CPU architecture, these may or may not exist:

   • C:\\Program Files (x86)\\Nodejs
   • C:\\Program Files\\Nodejs
   • C:\\Users{User}\\AppData\\Roaming\\npm (or %appdata%\\npm)
   • C:\\Users{User}\\AppData\\Roaming\\npm-cache (or %appdata%\\npm-cache)
   • C:\\Users{User}.npmrc (and possibly check for that without the . prefix too)

4. Check your %PATH% environment variable to ensure no references to Nodejs or npm exist.

5. Reboot the system and reinstall node JS.

Using NVM multiple versions of node js can be maintained
