使用VS2017还原NPM包时，因为要访问外网，安装时间特别漫长，而且等待很长时间也可能安装错误

npm安装

淘宝 NPM 镜像:一个完整 npmjs.org 镜像，你可以用此代替官方版本(只读)，同步频率目前为 10分钟 一次以保证尽量与官方服务同步。

安装淘宝镜像

1 npm config set registry https://registry.npm.taobao.org

2 npm info underscore

3 修改VS2017Npm外部配置工具

Npm配置默认选项

需要添加以下路径
C:\Program Files\nodejs
C:\Users\82511\AppData\Roaming\npm
D:\Program Files\Git\bin

配置淘宝镜像

再次还原npm,出现如下的安装信息。
