[webpack4] 使用webpack时报 Cannot find module 'webpack-cli'错误

使用webpack时报 Cannot find module 'webpack-cli’错误

今天遇到了个问题，明明我在项目中已经安装了webpck webpack-cli，但是在使用webpack命令打包时，依然报错。

webpack.config.js

{
  "name": "webpack-config-01",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "devDependencies": {
    "webpack": "4.26.0",
    "webpack-cli": "3.1.2"
  }
}

原因

可能你全局安装了webpack，但是并没有全局安装webpack-cli，所以在使用

webpack

命令时，首先调用的是全局安装的webpack，所以报错了

解决方法

全局安装webpack-cli

npm install -g webpack-cli

安装后，然后在调用webpack命令进行打包就可以了
