在node.js中有一个很棒的流控制模块叫做asyncblock。如果在函数中包装代码对您的情况是OK的，那么可以考虑以下示例:

var asyncblock = require('asyncblock');
var exec = require('child_process').exec;

asyncblock(function (flow) {
    exec('node -v', flow.add());
    result = flow.wait();
    console.log(result);    // There'll be trailing \n in the output

    // Some other jobs
    console.log('More results like if it were sync...');
});

您可以使用纤维来实现这一点。例如，使用我的Common Node库，代码看起来是这样的:

result = require('subprocess').command('node -v');

我也遇到过类似的问题，最后我为此写了一个节点扩展。您可以查看git存储库。它是开源的，免费的，还有所有这些好东西!

https://github.com/aponxi/npm-execxi

ExecXI是一个用c++编写的用于执行shell命令的节点扩展 依次将命令的输出输出到控制台中 实时的。有可选的链式和非链式方式;意义 您可以选择在命令失败后停止脚本 (被锁住)，或者你可以继续，就当什么都没发生!

使用说明在ReadMe文件中。请随意进行拉请求或提交问题!

编辑:但是它还没有返回标准输出…只是实时输出。现在有了。嗯，我今天刚刚发布。也许我们可以以此为基础。

不管怎样，我觉得值得一提。

你可以在nodejs中执行同步shell操作，如下所示:

var execSync = function(cmd) {

    var exec  = require('child_process').exec;
    var fs = require('fs');

    //for linux use ; instead of &&
    //execute your command followed by a simple echo 
    //to file to indicate process is finished
    exec(cmd + " > c:\\stdout.txt && echo done > c:\\sync.txt");

    while (true) {
        //consider a timeout option to prevent infinite loop
        //NOTE: this will max out your cpu too!
        try {
            var status = fs.readFileSync('c:\\sync.txt', 'utf8');

            if (status.trim() == "done") {
                var res = fs.readFileSync("c:\\stdout.txt", 'utf8');
                fs.unlinkSync("c:\\stdout.txt"); //cleanup temp files
                fs.unlinkSync("c:\\sync.txt");
                return res;
            }
        } catch(e) { } //readFileSync will fail until file exists
    }

};

//won't return anything, but will take 10 seconds to run
console.log(execSync("sleep 10")); 

//assuming there are a lot of files and subdirectories, 
//this too may take a while, use your own applicable file path
console.log(execSync("dir /s c:\\usr\\docs\\"));

编辑-本例适用于windows环境，如有必要可根据您自己的linux需求进行调整

我习惯于在回调函数的末尾实现“同步”的东西。不是很好，但是很有效。如果您需要实现一系列命令行执行，则需要将exec包装到某个命名函数中并递归调用它。 这个模式对我来说似乎很有用:

SeqOfExec(someParam);

function SeqOfExec(somepParam) {
    // some stuff
    // .....
    // .....

    var execStr = "yourExecString";
    child_proc.exec(execStr, function (error, stdout, stderr) {
        if (error != null) {
            if (stdout) {
                throw Error("Smth goes wrong" + error);
            } else {
                // consider that empty stdout causes
                // creation of error object
            }
        }
        // some stuff
        // .....
        // .....

        // you also need some flag which will signal that you 
        // need to end loop
        if (someFlag ) {
            // your synch stuff after all execs
            // here
            // .....
        } else {
            SeqOfExec(someAnotherParam);
        }
    });
};
