无法将命令“ webpack”替换为“ npm run build”

Question

请有人向我解释这一点。 我想使用命令npm run build来调用webpack。 所以我修改了文件package.json中的脚本。 但这没有用。 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

遵循指示

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

赶紧跑：

npm install webpack-cli -D -g

-g很好，然后尝试再次运行build，它应该可以工作:)

Answer 2

您没有将webpack-cli安装到devDependencies中

npm install webpack-cli -D

其实应该解决你的问题

也许您在全球范围内安装了webpack-cli，但不在您的devDependencies中

Answer 3

如果您直接像这样调用函数

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

从$ PATH中搜索Webpack作为命令。 使用npm install webpack-cli -D不会将其全局安装在$ PATH下，而是将其本地安装在./node_modules下。

因此，您有2个选择：

• 全局安装（-g）： npm -gi webpack-cli
• 从node_module目录运行它： node_modules/<path to webpack>

Answer 4

如果将webpack安装到项目中而不是全局安装，请尝试以下操作：

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