node.js listen to process error event

Question

有一种方法可以监听诸如process.stderr之类的节点进程的事件，我希望事件是当调用此行以在内部做一些逻辑时，是否有可能？

If you mean to listen to the child process spawned from your nodejs server, its simple, i have given the example below.

Note: its very unclear to guess what you mean

        var spawn = require('child_process').spawn;

        var child = spawn('myshell.sh', []);

        child.stdout.on('data', function(data) {
            console.log('stdout- ' + data);
        });
        child.stderr.on('data', function (data) {
            console.log('stderr- ' + data);
        });     
        child.on('exit', function (code) {
            console.log('exit - ' + code);
        });
