当时我的 webpack 和 webpack-dev-server版本如下：
"dependencies": {"webpack": "^5.4.0","webpack-dev-server": "^3.11.0","wepack-cli": "0.0.1-security"},
后来查了下可能是因为Webpack与webpack-dev-server版本不兼容导致，
//卸载版本cnpm uninstall webpack -gcnpm uninstall -g webpack-dev-server//安装指定版本cnpm install webpack@4.16.0 --save-devcnpm install webpack-dev-server@3.1.4 --save-dev
或者直接把代码粘进去
"dependencies": {"webpack": "^4.16.0","webpack-cli": "^3.0.8","webpack-dev-server": "^3.1.4"},
再输入npm install
最后输入:
webpack-dev-server --config=config/webpack.dev.js
打开地址发现成功了
