另一个文件夹中的Node_modules

我在C：/ Users / user / AppData / Roaming / npm / node_modules路径中有所有节点模块 . 然后我尝试为我的脚本webpack包含带有babel和babel-presets的node_modules .

我的webpack.config.js

module.exports = {
    context: './scripts',
    entry: ['./main', './2.jsx'],
    output: {
        path: '../scripts',
        filename: 'bundle.js',
    },
    resolve: {
        modulesDirectories: ['C:/Users/user/AppData/Roaming/npm/node_modules']
    },
    resolveLoader: {
        root: 'C:/Users/user/AppData/Roaming/npm/node_modules'
    },
    module: {
        loaders: [{
            test: /\.jsx?$/,
            loader: 'babel-loader',
            include: 'C:/Users/user/AppData/Roaming/npm/node_modules',
            exclude: /(node_modules|bower_components)/,
            query: {
                presets: ['es2015', 'react']
            }
        }],
    },
};

但是babel看不到预设的es2015 . 我也想到了预设的反应 .

webpack 命令重新调整：

ERROR in ../main.js Module build failed: Error: Couldn't find preset "es2015"

请帮忙 . 哪里出错了？
