Node.js npm package.json 操作系统特定脚本

发布于07月13日

我想创建一个package.json构建脚本，当在Windows、Linux和Mac上运行时，它会执行一组稍微不同的命令.

问题是，我无法找到一种方法将其放入package.json个文件中，以便在每个系统上都能正常运行.

下面是我想举的一个例子:

"scripts" : {
    "build.windows" : "echo do windows specific stuff",
    "build.linux" : "echo do linux specific stuff",
    "build.mac" : "echo do mac specific stuff",
    "build" : "??????????????" <- what to put here to execute script designed for OS
                                  on which npm is running
}

推荐答案

您可以使用node run-script命令的脚本.npm run是一条捷径.

包json:

"scripts" : {
    "build-windows" : "node build-windows.js",
    "build-linux" : "node build-linux.js",
    "build-mac" : "node build-mac.js",
    "build" : "node build.js"
}

命令行:

npm run build-windows

如果不喜欢，可以在 node 内部使用命令.js.

包json:

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

建筑js

var sys = require('sys');
var exec = require('child_process').exec;
var os = require('os');

function puts(error, stdout, stderr) { sys.puts(stdout) }

// Run command depending on the OS
if (os.type() === 'Linux') 
   exec("node build-linux.js", puts); 
else if (os.type() === 'Darwin') 
   exec("node build-mac.js", puts); 
else if (os.type() === 'Windows_NT') 
   exec("node build-windows.js", puts);
else
   throw new Error("Unsupported OS found: " + os.type());
