我的webpack配置可以在MacOS上运行，但它在Windows上显示错误。
webpack.config.js
var path = require("path");
var webpack = require("webpack");
var FileSystem = require("fs");
var argv = require('yargs').argv;
var ExtractTextPlugin = require('extract-text-webpack-plugin');
module.exports = {

function() {
this.plugin("done", function(statsData) {
var stats = statsData.toJson();
var bundlejs,maincss;
var mains = stats.assetsByChunkName.main;
console.log(mains);
for (var i = 0; i < mains.length; i++) {
if (/^(bundle).+(js)$/.test(mains[i])) {
bundlejs = mains[i]
}
if (/^(main).+(css)$/.test(mains[i])) {

}
if (!stats.errors.length) {
var htmlFileName = "index.html";
var html = FileSystem.readFileSync(path.join('./resources/temp', htmlFileName), "utf8");
var htmlOutput = html.replace('bundle.js', bundlejs).replace('main.css', maincss);
FileSystem.writeFileSync(path.join('./', htmlFileName), htmlOutput);

});

我的目录结构是：
+src
+app
+node_modules
+webpack.config.js
在MacOS上一切正常，但是当我在Windows上运行它时，我收到一个错误：
Module not found: Error: Cannot resolve module 'css' in somefile.
文件就像这样：
const style = require('./BuildingDetailContainer.scss');
我确信我已经安装了css-loader sass-loader style-loader
这是我的package.json，我怀疑它是由这个文件引起的。也许是因为我没有将我的加载器添加到依赖项中。

我在Windows上工作，让事情顺利运行是一场噩梦，一切都在Mac上工作正常，但在Windows上没有，所以如果这只是Windows和Sass的错误，你可能需要手动添加路径sass loader。
Windows上的技巧就在这里：
我正在使用sass loader 3.0，在我的webpack.config中它是这样的：
const path = require("path");
const srcPath = path.join(__dirname, 'src');
const sassLoaders = [
"css-loader",
"autoprefixer-loader?browsers=last 2 version",
"sass-loader?indentedSyntax=sass&includePaths[]=" + path.resolve(__dirname, "./src"),
];
我的package.json用于加载：
"autoprefixer-loader": "3.1.0"
"sass-loader": "^3.0.0",
"style-loader": "0.12.4"
我的决心使用path.sep在Windows中我必须这样做：
resolve: {
extensions: ["", ".js", ".scss"],
modulesDirectories: ["src", "node_modules"],
root: [__dirname + path.sep + 'scripts'],
}
作为一个抬头，对于我这样使用的装载机，我注意到你的模块中没有sass加载器：
{test: /\.scss$/, loaders: ["style", "css", "sass"]},
{test: /\.css$/, loader: ExtractTextPlugin.extract("style-loader", "css-loader")},
