npm-start

启动一个包

概要

¥Synopsis

npm start [-- <args>]

描述

¥Description

这将运行在包的 "scripts" 对象的 "start" 属性中指定的预定义命令。

¥This runs a predefined command specified in the "start" property of a package's "scripts" object.

如果 "scripts" 对象没有定义 "start" 属性，npm 将运行 node server.js。

¥If the "scripts" object does not define a "start" property, npm will run node server.js.

请注意，这与使用 node . 调用时运行包的 "main" 属性中指定的文件的默认 node 行为不同

¥Note that this is different from the default node behavior of running the file specified in a package's "main" attribute when evoking with node .

从 npm@2.0.0 开始，你可以在执行脚本时使用自定义参数。有关详细信息，请参阅 npm run-script。

¥As of npm@2.0.0, you can use custom arguments when executing scripts. Refer to npm run-script for more details.

示例

¥Example

{
  "scripts": {
    "start": "node foo.js"
  }
}

npm start

> npm@x.x.x start
> node foo.js

(foo.js output would be here)

配置

¥Configuration

ignore-scripts

• 默认值：false

  ¥Default: false

• 类型：布尔值

  ¥Type: Boolean

如果为 true，npm 不会运行 package.json 文件中指定的脚本。

¥If true, npm does not run scripts specified in package.json files.

请注意，如果设置了 ignore-scripts，则明确旨在运行特定脚本的命令（例如 npm start、npm stop、npm restart、npm test 和 npm run-script）仍将运行其预期的脚本，但它们不会运行任何前置或后置脚本。

¥Note that commands explicitly intended to run a particular script, such as npm start, npm stop, npm restart, npm test, and npm run-script will still run their intended script if ignore-scripts is set, but they will not run any pre- or post-scripts.

script-shell

• 默认值：'/bin/sh' 在 POSIX 系统上，'cmd.exe' 在 Windows 上

  ¥Default: '/bin/sh' on POSIX systems, 'cmd.exe' on Windows

• 类型：空值或字符串

  ¥Type: null or String

用于脚本的 shell 与 npm exec、npm run 和 npm init <package-spec> 命令一起运行。

¥The shell to use for scripts run with the npm exec, npm run and npm init <package-spec> commands.
