Node.js 未找到模块：错误：Can'；t解决'；巴别塔装载机&x27；

我刚把我的web包从2.x升级到4.x。通过执行npm安装，我得到了以下错误

Module not found: Error: Can't resolve 'babel-loader' 

接下来，我在webpack.config.json中添加了以下行

 resolveLoader: {   root: path.join(__dirname, 'node_modules') }

但是我犯了以下错误

Invalid configuration object. Webpack has been initialised using a configuration object that does not match the API schema.
 - configuration.resolveLoader has an unknown property 'modulesDirectories'. These properties are valid: object { alias?, aliasFields?, cachePredicate?, descriptionFiles?, enforceExtension?, enforceModuleExtension?, extensions?, fileSystem?, mainFields?, mainFiles?, moduleExtensions?, modules?, plugins?, resolver?, symlinks?, unsafeCache?, useSyncFileSystemCalls? }

巴别塔加载器版本是7.1.4。网页包升级引入了此错误。有什么建议吗

你不安装这个“巴别塔加载器”吗

只需安装模块：

npm安装巴别塔加载器

或

纱线添加巴别塔加载器

我通过运行上述命令解决了此问题。

您可以发布您的网页配置吗？我收到以下错误，模块解析失败：意外标记您可能需要适当的加载程序来处理此文件类型。
