Answer 1

In Webpack 2, resolvers from root, modulesDirectories, and fallback settings will merge into a single property – modules.

resolve.root, resolve.fallback, resolve.modulesDirectories
webpack2.x中上述三个选项将被合并为一个标准配置项：resolve.modules

resolve: {
    extensions: [".css", ".js", ".json"]
    modules: [
        "node_modules"

}

Answer 2

你那是webpack1的吧。 webpack2

请参考这个配。
