如何重置nodejs流？如何在nodejs中再次读取流？提前致谢!

var fs = require('fs');
var lineReader = require('line-reader');

// proxy.txt = only 3 lines

var readStream = fs.createReadStream('proxy.txt');
lineReader.open(readStream, function (err, reader) {
    for(var i=0; i<6; i++) {
        reader.nextLine(function(err, line) {
            if(err) {
                readStream.reset(); // ???
            } else {
                console.log(line);
            }
        });
    }
});
