使用angular/cli设置新项目时出错 [英] Error setting up new project with angular/cli
问题描述
我是npm和Angular 2的新手，我正在尝试使用angular/cli建立一个新的Angular 2项目.
I am new to npm and Angular 2, I am trying to setup a new Angular 2 project using angular/cli.
我当前正在跑步:
节点v8.9.3 npm v5.6.0 Windows 10
Node v8.9.3 npm v5.6.0 Windows 10
首先，我运行了npm install -g @angular/cli，它似乎安装得很好.然后我转到要启动项目的文件夹，运行ng new my-app，但一直收到此错误.
First, I ran npm install -g @angular/cli which seemed to install just fine. Then I went to the folder where I wanted to start my project, ran ng new my-app but kept getting this error.

推荐答案
从命令行运行
ng -v
这应该输出1.6.0.如果不是，则说明您安装了较旧版本的CLI.
This should output 1.6.0. If it doesn't you have an older version of the CLI installed.
运行:
npm cache --force clean
然后:
npm install @angular/cli -g
如果这样不起作用，请删除C:\Users\<username>\AppData\Roaming
If that doesnt work remove the folders in C:\Users\<username>\AppData\Roaming
