这对我来说很好

var osvar = process.platform;

if (osvar == 'darwin') {
    console.log("you are on a mac os");
}else if(osvar == 'win32'){
    console.log("you are on a windows os")
}else{
    console.log("unknown os")
}

var isWin64 = process.env.hasOwnProperty('ProgramFiles(x86)');

当你在64位窗口上使用32位节点时(如node-webkit或atom-shell开发人员)，处理。平台将回显win32

use

    function isOSWin64() {
      return process.arch === 'x64' || process.env.hasOwnProperty('PROCESSOR_ARCHITEW6432');
    }

(详情请点击此处)

const path = require('path');

if (path.sep === "\\") {
console.log("Windows");
} else {
console.log("Not Windows");
}

对我来说没问题

if (/^win/i.test(process.platform)) {
    // TODO: Windows
} else {
    // TODO: Linux, Mac or something else
}

修饰符i用于进行不区分大小写的匹配。

过程

var opsys = process.platform;
if (opsys == "darwin") {
    opsys = "MacOS";
} else if (opsys == "win32" || opsys == "win64") {
    opsys = "Windows";
} else if (opsys == "linux") {
    opsys = "Linux";
}
console.log(opsys) // I don't know what linux is.

OS

const os = require("os"); // Comes with node.js
console.log(os.type());
