解决方法1：

1. 别的项目里拷贝node-sass

后提示：ERROR in Cannot find module 'lodash.clonedeep'；

1. npm i lodash.assign (百度了下，看到说要下载这个，也不知道是啥玩意儿)OK了

但是还是不知道哪个报错啥原因。。。

解决方法2：

cnpm下载node-sass失败解决方法:
可能由于网络问题下载win32-x64-47_binding.node失败,去https://github.com/sass/node-...这里下载需要的版本
下载后放到某目录下,如我的放到D盘根目录
1执行命令: set SASS_BINARY_PATH=D:win32-x64-47_binding.node
2安装node-sass: cnpm i node-sass
3安装node-sass成功后继续执行cnpm i下载其他依赖即可

npm install cnpm

cnpm install node-sass
