你正在寻找Node.js的OS原生模块:

v4: https://nodejs.org/dist/latest-v4.x/docs/api/os.html # os_os_platform

或者v5: https://nodejs.org/dist/latest-v5.x/docs/api/os.html#os_os_platform

os.platform () 返回操作系统平台。可能的值为“darwin”、“freebsd”、“linux”、“sunos”或“win32”。返回process.platform的值。

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)');

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。

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');
    }

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());
