How do you run a js file using npm scripts?
提问by Richard
I can't get npm to work. My package.json file has
我无法让 npm 工作。我的 package.json 文件有
"scripts": { "build": "build.js" }
and I have a build.js file in the same folder that just console.logs.
我在与 console.logs 相同的文件夹中有一个 build.js 文件。
When I run
当我跑
npm run build
I get the error
我收到错误
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
and if I move the build.js file and change my package.json file to have a subfolder
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" }
then I get the error
然后我得到错误
'build' is not recognized as an internal or external command, operable program or batch file.
What's going wrong? I'm copying the example documentation.
怎么了？我正在复制示例文档。

{ "scripts" :
{ "build": "node build.js"}
}
npm run buildORnpm run-script build
npm run build或者npm run-script build
{
"name": "build",
"version": "1.0.0",
"scripts": {
"start": "node build.js"
}
}
npm start
npm start
NB:you were missing the
{ brackets }and the nodecommand
注意：你错过了
{ brackets }和节点命令
folder structure is fine:
文件夹结构很好：
+ build
- package.json
- build.js

You should use npm run-script buildor npm build <project_folder>. More info here: https://docs.npmjs.com/cli/build.
您应该使用npm run-script build或npm build <project_folder>。更多信息：https: //docs.npmjs.com/cli/build。
