Angular-cli 无法正确安装

Question

I wonder if you can help me.

I tried to install the angular-cli by the npm command

npm install -g angular-cli, however I got a lot of messages, and 'ng' command does not work.

Some of the errors I got are as following

Answer 1

I am not on Windows but what you should consider doing first, run command line with administrative privileges. select the application on secondary menu (right click) select runs as admin.

Before that make sure you have installed the latest version of node.js. and the run the following commands.

npm uninstall -g angular/cli npm cache clean npm install -g angular/cli@latest

Answer 2

An update on this. I installed the new node.js V6.6.0, uninstalled the Angular-Cli, cleaned cache and re-installed the clie and it seems to have done the trick since I was able to install the Angular-CLI without problems this time, and ng new is working.

Answer 3

set environment variable PYTHON , with value of full path where python.exe is installed. If its C:\\Program Files\\Python34\\ then value will be C:\\Program Files\\Python34\\python.exe
