如何在 package.json 中从另一个命令调用一个命令? [英] How to call one command from another in package.json?

问题描述

假设我在 package.json 中有一些这样的脚本

suppose if i have some script in package.json like this

 "scripts": {
    "a1": "first command",
    "a2": "second command",
    "a3": "third command",
      
  }

如果我想在脚本 a3 中运行脚本 a1 和 a2 我该怎么做?这可能吗?我正在使用

and if i want to run script a1 and a2 in the script a3 how can i do this? can this be possible? I am using

节点版本:v6.9.4

node version : v6.9.4

npm 版本:4.3.0

npm version : 4.3.0

我想实现这样的目标

"scripts": {
    "a1": "first command",
    "a2": "second command",
    "a3": "third command && a1 && a2",
      
  }

推荐答案

在脚本中使用 npm run.例如

"scripts": {
  "a1": "first command",
  "a2": "second command",
  "a3": "third command && npm run a1 && npm run a2",
}

通过 CLI 运行 $ npm run a3 将运行 第三个命令(不管是什么)，然后是 a1，然后是 a2.

Running $ npm run a3 via the CLI will run the third command (whatever that is), followed by a1, then a2.

但是，如果通过 CLI 运行 $npm run a3 只是运行 a1 后跟 a2 那么:

However, if running $npm run a3 via the CLI is to only run a1 followed by a2 then:

"scripts": {
  "a1": "first command",
  "a2": "second command",
  "a3": "npm run a1 && npm run a2",
}
