Node.js to get/determine OS version
提问by badunk
I'd like to determine whether some script that is being executed is running a particular version of Mac OSX. I realize I can exec/spawn the command:
我想确定正在执行的某个脚本是否正在运行特定版本的 Mac OSX。我意识到我可以执行/生成命令：
sw_vers -productVersion
Is there a way to do this synchronously (similar to process.arch) without node-exec-sync? I realize its an accepted bad practice to spawn/exec synchronously, but I don't see another way.
有没有办法在没有node-exec-sync 的情况下同步执行此操作（类似于 process.arch）？我意识到同步生成/执行是一种公认的不良做法，但我没有看到其他方式。

you could use the OS modulelike this:
你可以像这样使用 OS 模块：
var os = require('os');
os.platform(); // 'darwin'
os.release(); //'10.8.0'
and then map the release version to a specific version of Mac OS X.
然后将发布版本映射到特定版本的 Mac OS X。

As mentioned above in AndyD's answer's comments, os.release()returns the kernel version. If you want to get the same version number that a user sees in the "About this Mac" UI, you can read and parse out /System/Library/CoreServices/SystemVersion.plist, like so:
正如上面在 AndyD 的回答评论中提到的，os.release()返回内核版本。如果您想获得用户在“关于此 Mac”用户界面中看到的相同版本号，您可以读取并解析出/System/Library/CoreServices/SystemVersion.plist，如下所示：
const plist = require('plist');
let versionInfo = plist.parseFileSync('/System/Library/CoreServices/SystemVersion.plist');
console.log(JSON.stringify(versionInfo));
