另一個文件夾中的 Node_modules

Question

我在C:/Users/user/AppData/Roaming/npm/node_modules路徑中有所有節點模塊。 然后我嘗試為我的腳本 webpack 包含帶有 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 沒有看到預設es2015 。 我也認為預設反應。

webpack命令返回：

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

請幫忙。 錯誤在哪里？

npm link <pkg>
