无法将命令 'webpack' 替换为 'npm run build'

Question

请有人给我解释一下。我想使用命令 npm 运行 build 来调用 webpack。所以我修改了文件package.json中的脚本。但它没有用。我正在使用 linux

这是我的 package.json 文件

{
  "name": "learn-webpack",
  "version": "1.0.0",
  "description": "Learn Webpack",
  "main": "index.js",
  "scripts": {
    "build": "webpack"
  },
  "author": "",
  "license": "ISC",
  "devDependencies": {
    "babel-core": "^6.26.0",
    "babel-loader": "^7.1.4",
    "babel-preset-env": "^1.6.1",
    "css-loader": "^0.28.11",
    "style-loader": "^0.20.3",
    "webpack": "^4.2.0"
  }
}

这是错误，它已经安装了 cli 但它一直发送此消息

The CLI moved into a separate package: webpack-cli.
Please install 'webpack-cli' in addition to webpack itself to use the CLI.
-> When using npm: npm install webpack-cli -D
-> When using yarn: yarn add webpack-cli -D

Answer 1

如果您将 webpack 安装到您的项目中而不是全局安装，试试这个：

"build": "./node_modules/webpack/bin/webpack"

Answer 2

按照说明进行操作

The CLI moved into a separate package: webpack-cli.

Please install 'webpack-cli' in addition to webpack itself to use the CLI.

-> When using npm: npm install webpack-cli -D

就运行:

npm install webpack-cli -D -g

-g 为了更好的衡量，然后再次尝试运行ning 构建，它应该可以工作:)

Answer 3

您没有将 webpack-cli 安装到您的 devDependencies

npm install webpack-cli -D

其实应该可以解决你的问题

也许您已全局安装 webpack-cli，但它不在您的 devDependencies 中

Answer 4

如果你像

一样直接调用一个函数

  "scripts": {
    "build": "webpack"
  },

从您的 $PATH 搜索 Webpack 作为命令。使用 npm install webpack-cli -D 不是全局安装在 $PATH 下，而是本地安装在 ./node_modules.

下

因此你有2个选择：

全局安装（-g）：npm -g i webpack-cli
运行它来自 node_module 目录：node_modules/<path to webpack>
