另一个文件夹中的Node_modules

我有C：/ Users / user / AppData / Roaming / npm / node_modulespath中的所有节点模块。 然后，我正在尝试为我的脚本webpack添加包含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没有看到预设es2015 。 预设的反应也是我想的。

webpack命令重新调整这个：

 ERROR in ../main.js Module build failed: Error: Couldn't find preset "es2015" at OptionManager.mergePresets (C:\Users\user\AppData\Roaming\npm\node_modules\babel-core\lib\transformation\file\options\option-manager.js:329:17) at OptionManager.mergeOptions (C:\Users\user\AppData\Roaming\npm\node_modules\babel-core\lib\transformation\file\options\option-manager.js:289:12) at OptionManager.init (C:\Users\user\AppData\Roaming\npm\node_modules\babel-core\lib\transformation\file\options\option-manager.js:414:10) at File.initOptions (C:\Users\user\AppData\Roaming\npm\node_modules\babel-core\lib\transformation\file\index.js:191:75) at new File (C:\Users\user\AppData\Roaming\npm\node_modules\babel-core\lib\transformation\file\index.js:122:22) at Pipeline.transform (C:\Users\user\AppData\Roaming\npm\node_modules\babel-core\lib\transformation\pipeline.js:42:16) at transpile (C:\Users\user\AppData\Roaming\npm\node_modules\babel-loader\index.js:14:22) 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？
