WebPack:未定义的变量

Question

当我执行时，我正在处理这个问题：

webpack --config config/webpack.prod.js  --progress --profile --bail

它转储的消息是： path is not defined。

D:projectslivinguser-platformprojectconfigwebpack.prod.js:196
            resourcePath: path.resolve(projectRoot, appConfig.root)
                          ^
ReferenceError: path is not defined

    at startup (bootstrap_node.js:139:9)

这些是我的WebPack配置文件：

• webpack.common.js
• webpack.dev.js
• webpack.prod.js

似乎是一个简单的问题。您可以尝试在顶部的某个地方添加它，看看一切是否有效：

var path = require('path');
