Question

我在 C：/ Users / user / AppData / Roaming / npm / node_modules 路径中有所有节点模块。然后我尝试将包含babel和babel-presets的node_modules包含在我的脚本webpack中。

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没有看到预设 es2015 。并预设了反应我也想。

webpack命令重新调整：

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

    at Object.module.exports (C:\Users\user\AppData\Roaming\npm\node_modules\babel-loader\index.js:83:14) @ multi main

请帮助。错误在哪里？
