Node.js内存泄漏

我正在获得内存泄漏，我不知道为什么。它是基于以前的脚本，我做的工作很好。我所做的只是更改了变量的名称，并更改了其中一个变量的值。

这是导致内存泄漏的代码。

console.log("Mine plugin started.")
var mineflayer = require('mineflayer');
var vec3 = mineflayer.vec3;
module.exports.inject = inject;
function inject(bot) {
var Mine = false
bot.on('whisper', function (username, message) {
    if (username == bot.username) return;
    if (message == 'mine') {
        Mine = true
        gotoBlo()
}
    if (message == 'stop') {
        Mine = false
}
});
function gotoBlo() {
    if (Mine = true) {
        posBlo = bot.entity.position;
        blockBlo = findBlock('diamond_ore', 8, posBlo);
        if (blockBlo != null) {
        var tempVar = vec3(blockBlo.position.x, blockBlo.position.y, blockBlo.position.z);
        bot.scaffold.to(tempVar)
        setTimeout(gotoBlo,5000)
        }
    }
}
function findBlock(type, size, point) {
    var block = null;
    var shortest = null;
    var x1 = Math.floor(point.x - size);
    var x2 = Math.floor(point.x + size);
    var y1 = Math.floor(point.y - size);
    var y2 = Math.floor(point.y + size);
    var z1 = Math.floor(point.z - size);
    var z2 = Math.floor(point.z + size);
    //bot.chat(x1 + "");
    for (x = x1; x < x2; x++) {
        for (y = y1; y < y2; y++) {
            for (z = z1; z < z2; z++) {
                var cPoint = vec3(x, y, z);
                var cBlock = bot.blockAt(cPoint);
                //bot.chat(cPoint + "");
                if (cBlock) {
                    //bot.chat(cBlock.name);
                    if (cBlock.name == type) {
                        if ((shortest > cPoint.distanceTo(point)) || shortest == null) {
                            shortest = cPoint.distanceTo(point);
                            block = cBlock;
                        }
                    }
                }
            }
        }
    }
    return block;
}
}

下面是运行良好的代码:

console.log("Defuse plugin started.")
var mineflayer = require('mineflayer');
var vec3 = mineflayer.vec3;
module.exports.inject = inject;
function inject(bot) {
var Disarm = false
bot.on('whisper', function (username, message) {
    if (username == bot.username) return;
    if (message == 'defuse') {
        disarm = true
        gotoTNT()
}
    if (message == 'stop') {
        disarm = false
}
});
function gotoTNT() {
    if (disarm = true) {
        posTNT = bot.entity.position;
        blockTNT = findBlock('tnt', 32, posTNT);
        if (blockTNT != null) {
        var tempVar = vec3(blockTNT.position.x, blockTNT.position.y, blockTNT.position.z);
        bot.scaffold.to(tempVar)
        setTimeout(gotoTNT,5000)
        }
    }
}
function findBlock(type, size, point) {
    var block = null;
    var shortest = null;
    var x1 = Math.floor(point.x - size);
    var x2 = Math.floor(point.x + size);
    var y1 = Math.floor(point.y - size);
    var y2 = Math.floor(point.y + size);
    var z1 = Math.floor(point.z - size);
    var z2 = Math.floor(point.z + size);
    //bot.chat(x1 + "");
    for (x = x1; x < x2; x++) {
        for (y = y1; y < y2; y++) {
            for (z = z1; z < z2; z++) {
                var cPoint = vec3(x, y, z);
                var cBlock = bot.blockAt(cPoint);
                //bot.chat(cPoint + "");
                if (cBlock) {
                    //bot.chat(cBlock.name);
                    if (cBlock.name == type) {
                        if ((shortest > cPoint.distanceTo(point)) || shortest == null) {
                            shortest = cPoint.distanceTo(point);
                            block = cBlock;
                        }
                    }
                }
            }
        }
    }
    return block;
}
}
