[JavaScript知识库]Module not found: Error: Can‘t resolve ‘path‘ in ‘/Users/wangabai/Desktop/学习/vue/code/vue3.2-element

Module not found: Error: Can’t resolve ‘path’ in ‘/Users/wangabai/Desktop/学习/vue/code/vue3.2-element-plus/src/utils’

提示 BREAKING CHANGE: webpack < 5 used to include polyfills for node.js core modules by default.
This is no longer the case. Verify if you need this module and configure a polyfill for it.
（webpack < 5默认用于包含node.js核心模块的polyfills。现在情况已经不一样了。验证你是否需要这个模块，并为它配置一个polyfill。）

If you want to include a polyfill, you need to:
- add a fallback ‘resolve.fallback: { “path”: require.resolve(“path-browserify”) }’
- install ‘path-browserify’
If you don’t want to include a polyfill, you can use an empty module like this:
resolve.fallback: { “path”: false }
（如果你想要包含一个polyfill，你需要:
-添加一个 ‘resolve.fallback: { “path”: require.resolve(“path-browserify”) }’
—install ‘path-browserify’
如果你不想包含polyfill，你可以像这样使用一个空模块:
resolve.fallback: { “path”: false }）

根据提示，我在vue.config.js里面添加了

  resolve: {
    fallback: { path: require.resolve('path-browserify') }
  }

结果报错 ERROR Invalid options in vue.config.js: “resolve” is not allowed

原因是我用的vue-cli5.0创建的项目，已经没有了原有的webpack配置，只有vue.config.js

最后把配置放在了configureWebpack即可解决

  configureWebpack: {
    resolve: {
      fallback: { path: require.resolve('path-browserify') }
    }
  }
