How Do You Run a Js File Using Npm Scripts?
I Can't Get Npm to Work. My Package. Json File Has "Scripts": { "Build": "Build. Js" } and I Have a Build. Js File in the Same Folder That Just Console. Logs...
I can't get npm to work. My package.json file has
"scripts": { "build": "build.js" }
and I have a build.js file in the same folder that just console.logs.
When I run
npm run build
I get the error
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
"scripts": { "build": "build/build.js" }
then I get the error
'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.

{ "scripts" :
{ "build": "node build.js"}
}
npm run buildORnpm 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
folder structure is fine:
+ build
- package.json
- build.js
You should use npm run-script build or npm build <project_folder>. More info here: .
