看下面，发现是npm 的 shasum check failed，查资料发现，可能是因为NPM未更换国内淘宝镜像所致....换一下
镜像使用方法（三种办法任意一种都能解决问题，建议使用第三种，将配置写死，下次用的时候配置还在）:
1.通过config命令
npm config set registry http://registry.cnpmjs.org
npm info underscore （如果上面配置正确这个命令会有字符串response）
2.命令行指定
npm --registry http://registry.cnpmjs.org info underscore
3.编辑 ~/.npmrc 加入下面内容
registry = http://registry.cnpmjs.org
我选用了第一种方法，然后成功安装。
