javascript - 如何使用 npm 脚本运行 js 文件？

Question

我无法让 npm 工作。我的 package.json 文件有

"scripts": { "build": "build.js" }

我在与 console.logs 相同的文件夹中有一个 build.js 文件。

当我运行时

npm run build

我得到了错误

The system cannot execute the specified program.

npm ERR! Windows_NT 6.1.7601
npm ERR! argv "C:\\Program Files\\nodejs\\node.exe" "C:\\Program Files\\nodejs\\node_modules\\npm\\bin\\npm-cli.js" "run" "build"
npm ERR! node v4.1.1
npm ERR! npm  v3.3.5
npm ERR! code ELIFECYCLE

如果我移动 build.js 文件并将我的 package.json 文件更改为有一个子文件夹

"scripts": { "build": "build/build.js" }

然后我得到错误

'build' is not recognized as an internal or external command, operable program or batch file.

怎么了？我正在复制 example documentation .

Answer 1

{ "scripts" :
  { "build": "node build.js"}
}

npm run build OR npm run-script build

---

{
  "name": "build",
  "version": "1.0.0",
  "scripts": {
    "start": "node build.js"
  }
}

npm start

NB: you were missing the { brackets } and the node command

文件夹结构很好:

+ build
  - package.json
  - build.js
