npm run dev没反应

问题遇到的现象和发生背景

直接运行webpack可以生成dist文件夹，npm run dev 不能生成dist文件夹

问题相关代码，请勿粘贴截图

package.json的内容：
{
"name": "280.webpack",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"test": "echo "Error: no test specified" && exit 1",
"dev": "webpack"
},
"keywords": [],
"author": "",
"license": "ISC",
"dependencies": {
"jquery": "^3.6.0"
},
"devDependencies": {
"webpack": "^5.5.1",
"webpack-cli": "^4.2.0"
}
}

运行结果及报错内容

npm run dev没有dist生成，终端的结果如下：

PS D:\My_college\web\280.webpack> npm run dev

280.webpack@1.0.0 dev
webpack

Microsoft Windows [版本 10.0.19044.1889]

webpack有dist生成，终端的结果如下：
D:\My_college\web\280.webpack>webpack
[webpack-cli] Compilation finished
asset main.js 324 KiB [emitted] (name: main)
runtime modules 931 bytes 4 modules
cacheable modules 282 KiB
./src/index.js 354 bytes [built] [code generated]
./node_modules/jquery/dist/jquery.js 282 KiB [built] [code generated]
webpack 5.5.1 compiled successfully in 300 ms

我的解答思路和尝试过的方法

重新初始化了几次文件夹，还是一样的结果

我想要达到的结果

npm run dev也可以生成dist文件夹

npm run build

npm run build

你的webpack.config.js的配置截图下，我试了下webpack跟直接配置dev:'webpack'都是能生成dist的
