当用户输入低于最小值时，脚本立即关闭，而不是再次提示

Question

我正在制作一个最少有5名玩家的游戏。

如果用户输入的值小于5，则应告知最小值为5，然后再次提示。

我的代码在用户输入为> = 5时起作用，但是在输入低于5时立即关闭，而不是执行应有的操作。

const readline = require('readline');

var players = []

var rl = readline.createInterface(process.stdin, process.stdout);

var playerNumber

//takes user input of how many players to prompt names for player 1, player 2, etc.
function readPlayers(playerCount, playerArr, curr = 0) {
    if (playerCount < 5 || playerCount == curr) { //error is either found here
        rl.close();
        return;
    }

    rl.question("Enter name of player " + (curr + 1) + ": ", function (playerName) {
        playerArr.push(playerName)
        readPlayers(playerCount, playerArr, curr + 1);
    });
}

function numberAndNames() {

    rl.question("Enter number of players: ", function (answer) {

        readPlayers(parseInt(answer), players);
        var playerNumber = answer
    });

    rl.on('close', function () {
        if (playerNumber < 5) { //or error is found here
            console.log("Insuficient players. A minimum of 5 players is required.")
            numberAndNames();
        } else {
        console.log("The players are: " + players.toString());
        }
    });
}

numberAndNames();
