vue+sass 下sass不能运行问题

好久没写博文了，今天抽空写一写，最近在用vue.js build 项目，今早想使用sass来编译css,可是安装好依赖包之后仍然显示一下错误：

ERROR in ENOENT: no such file or directory, scandir '/Users/baidu/Documents/mydata/hfutoj/node_modules/.npminstall/node-sass/3.8.0/node-sass/vendor'
 @ ./~/vue-style-loader!./~/css-loader!./~/vue-loader/lib/style-rewriter.js!./~/.npminstall/sass-loader/4.0.0/sass-loader!./~/vue-loader/lib/selector.js?type=style&index=0!./src/components/footer.vue 4:14-273 13:2-17:4 14:20-279

　　我vue component 里面是这样用的：

代码语言：javascript复制

<style lang="scss">
.footer {
  margin-top: 3em;
  padding-top: 2em;
  border-top: 1px solid #ccc;
  text-align: center;
  font-size: 1em;
  clear: both;
  height: 4em;}
</style>

　我心想不应该啊，我依赖包都安装了，需要的依赖包是：node-sass ,sass-loader,vue-style-loader，css-loader，分析了下，觉得是node-sass没安装好，所以我就卸载了node-sass，然后又重新安装（注意cnpm是需要使用npm安装的，这个好像是淘宝的镜像，比较快）：

代码语言：javascript复制

npm remove node-sass
cnpm install node-sass

　　package.json里是这样写的：

    "webpack-dev-middleware": "^1.4.0",
    "webpack-hot-middleware": "^2.6.0",
    "webpack-merge": "^0.8.3"
  }
}

　　但是，仍然报错，为毛？我发现重装之后错误并没有变，仍然是.npminstall 下面的文件没被找到，所以.npminstall（这是个隐藏文件）下的文件并没有被卸载，所以我决定把整个node_modules删除了再重装（cnpm install），之后就好了，不过我把ndoe-sass的版本号由3.8.0换成了3.7.0

sass vue.js npm
