如何解决Windows中的“ npm ERR！code ELIFECYCLE”错误

问题描述

我正在学习javascript，为此，我正在新项目上配置webpack。 当我运行“ webpack脚本”（在package.json中）时，它可以正常运行，但不适用于“启动脚本”。而且我收到此错误“ npm ERR！code ELIFECYCLE”。我测试了在此论坛上看到的一些解决方案（1.npm缓存清理--force，2.delete package.json和节点模块3.npm安装，npm启动），但仍然无法使用。

我的package.json：

{
  "name": "todoProject","version": "1.0.0","description": "","main": "index.js","scripts": {
    "test": "echo \"Error: no test specified\" && exit 1","webpack": "webpack","start": "webpack-dev-server"
  },"keywords": [],"author": "","license": "ISC","dependencies": {
    "@babel/cli": "^7.12.1","@babel/core": "^7.12.3","@babel/preset-env": "^7.12.1","babel-loader": "^8.1.0","html-webpack-plugin": "^4.5.0","webpack": "^5.1.3","webpack-cli": "^4.1.0","webpack-dev-server": "^3.11.0"
  }
}

我的webpack.config.js：

const path = require("path");
const HtmlWebpackPlugin = require("html-webpack-plugin");

module.exports = {
  entry: {
    main: path.join(__dirname,"src/index.js")
  },output: {
    path: path.join(__dirname,"dist"),filename: "[name].bundle.js"
  },module: {
    rules: [
      {
        test: /\.js/,exclude: /(node_modules)/,use: ["babel-loader"]
      }
    ]
  },plugins: [
    new HtmlWebpackPlugin({
      template: path.join(__dirname,"./src/index.html")
    })
  ],stats: "minimal",devtool: "source-map",mode: "development",devServer: {
    open: false,contentBase: "./dist",inline: true,port: 4000
  }
};

错误：

解决方法

使用npm运行脚本：

05:27:56
05:27:57
05:27:58

不是

npm start

也许webpack-dev-server 未全局安装？
