1. 出现问题描述

npm run serve 项目时报错

 ERROR  Failed to compile with 1 error                                                                           10:33:22 ├F10: AM┤

 error  in ./src/router/routes.js

Module not found: Error: Can't resolve 'path' in '/Users/guolijun/Desktop/vue-oil-enterprise/src/router'

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.

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 }
