原因分析：

1.0版本问题

Version compatibility could be the issue. Downgrading node js version from 16.8.0 to 14.17.5 resolved my issue.

2.0

This is packaged as a standalone npm module. To use in node, monkeypatch HTTPParser.,http-parser-js should work via monkey-patching on Node v6-v11, and v13., We found a way for you to contribute to the project! Looks like http-parser-js is missing a security policy. , In the past month we didn't find any pull request activity or change in issues status has been detected for the GitHub repository.

执行语句

npm install http - parser - js

报错说明这些包版本太低了

npm WARN deprecated uuid@3.4.0: Please upgrade  to version 7 or higher.  Older versions may use Math.random() in certain circumstances, which is known to 
be problematic.  See https://v8.dev/blog/math-random for details.
npm WARN deprecated uglify-es@3.3.9: support for ECMAScript is superseded by `uglify-js` as of v3.13.0
npm WARN deprecated svgo@1.0.5: This SVGO version is no longer supported. Upgrade to v2.x.x.

3.0报错说

webpack-dev-server --inline --progress --config build/webpack.dev.conf.js
原因：新版的webpack-dev-server 3.1.14 存在问题。

解决方法：package.json 中指定 webpack-dev-server 低版本号

方法1：

“webpack-dev-server”: “^2.9.1”

删除 node_modules 目录，再重新安装依赖包

npm install -S // 这种方式安装的时间会长些，也可以只重装 webpack-dev-server模块

方法2：单独重装 webpack-dev-server模块

（1）、npm uninstall webpack-dev-server

（2）、npm install webpack-dev-server@2.9.1

（3）、npm run dev

解决方案：

每次报错都不一样可真行啊
