今天起server的时候发现，scss加载报错，仔细检查发现是loader顺序写错了，贴一个官网的例子：
require("!style!css!less!bootstrap/less/bootstrap.less");
//=> the file "bootstrap.less" in the folder "less" in the "bootstrap"
//module (that is installed from github to "node_modules") is
//transformed by the "less-loader". The result is transformed by the
//"css-loader" and then by the "style-loader".
//If configuration has some transforms bound to the file, they will not be applied.
写的很明确了，加载顺序是从后向前，比如要加载scss文件，要把scss写在最后
