问题描述
我正在使用 npm+webpack 来管理 React Web 应用程序.我想为 npm 定义一些命令以便运行一些 webpack 命令.下面是我在 package.json 文件中定义的两个命令脚本.
I am using npm+webpack to manage a react web application. And I want to define a few command for npm in order to run some webpack command. Below is the two command scripts I defined in package.json file.
"scripts": {
"start": "webpack-dev-server --host 0.0.0.0",
"build": "NODE_ENV=production webpack --config ./webpack.config.js --progress --profile --colors"
},
如您所见，有两个命令start"和build".当我运行 npm start 时，它会运行 webpack-dev-server --host 0.0.0.0 来启动一个网络服务器.但是当我运行 npm build 时，它不会运行配置的命令，只是返回而没有任何输出.我想知道如何定义一个供 npm 使用的脚本命令.下面是我的整个 package.json 文件:
As you can see, there are two commands 'start' and 'build'. When I run npm start it will run webpack-dev-server --host 0.0.0.0 to launch a web server. But when I run npm build, it doesn't run the configured command and simply returns without any output. I wander how to define a script command for npm to use. Below is my whole package.json file:

"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"start": "webpack-dev-server --host 0.0.0.0",
"build": "NODE_ENV=production webpack --config ./webpack.config.js --progress --profile --colors"

推荐答案
您可以使用 npm run-script 来运行任意脚本.在您的情况下，npm run-script build.
You can use npm run-script <script-name> to run arbitrary scripts. In your case, npm run-script build.
从 npm 文档来看，npm 语法仅支持特定数量的预定脚本，例如 start.
From the npm documentation, The npm <script-name> syntax is only supported for a specific number of predetermined scripts such as start.
npm 支持 package.json 脚本的 "scripts" 属性，用于以下脚本:
- prepublish:在发布包之前运行.(也可以在没有任何参数的情况下在本地 npm install 上运行.)
- publish、postpublish:在发布包后运行.
- 预安装:在安装包之前运行
- 安装、安装后:安装包后运行.
- 预卸载、卸载:在卸载包之前运行.
- postuninstall:在卸载软件包后运行.
- preversion、version:在修改包版本之前运行.
- postversion:在修改包版本后运行.
- 预测试、测试、后测试:通过 npm test 命令运行.
- prestop、stop、poststop:通过 npm stop 命令运行.
- prestart、start、poststart:通过 npm start 命令运行.
- prerestart、restart、postrestart:通过 npm restart 命令运行.注意:如果没有提供重启脚本，npm restart 将运行停止和启动脚本.
另外，任意脚本可以通过运行npm run-script <pkg>.具有匹配名称的前置和后置命令也将针对那些运行(例如 premyscript、myscript、postmyscript).
Additionally, arbitrary scripts can be executed by running npm run-script <pkg> <stage>. Pre and post commands with matching names will be run for those as well (e.g. premyscript, myscript, postmyscript).
同样，您可以使用 npm run 作为速记.
As well, you can use npm run <script-name> as a shorthand.
