更改前package.json文件

{
    
    
  "name": "djangomall",
  "version": "0.0.0",
  "description": "djangomall app",
  "main": "index.js",
  "scripts": {
    
    
    "watch": "webpack --mode=development --progress --watch",
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "jacky",
  "license": "ISC",
  "devDependencies": {
    
    
    "cross-env": "^7.0.2",
    "webpack": "^4.43.0",
    "webpack-bundle-tracker": "^0.4.3",
    "webpack-cli": "^3.3.11"
  }
}

运行npm run watch后报错

Error: error:0308010C:digital envelope routines::unsupported

解决办法：开启 legacy OpenSSL provider，在package.json文件的scripts中添加如下命令，Windows解决办法如下：

set NODE_OPTIONS=–openssl-legacy-provider &&

更改后的package.json文件如下：

{
    
    
  "name": "djangomall",
  "version": "0.0.0",
  "description": "djangomall app",
  "main": "index.js",
  "scripts": {
    
    
    "watch": "set NODE_OPTIONS=--openssl-legacy-provider && webpack --mode=development --progress --watch",
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "jacky",
  "license": "ISC",
  "devDependencies": {
    
    
    "cross-env": "^7.0.2",
    "webpack": "^4.43.0",
    "webpack-bundle-tracker": "^0.4.3",
    "webpack-cli": "^3.3.11"
  }
}

Linux下如下：export NODE_OPTIONS=--openssl-legacy-provider

报错原因猜测：使用了高版本的Node.js，然后使用了webpack4，我的Node.js是 v18.15.0
