奇怪 "count property undefined"

Question

我需要这方面的帮助，老实说，我已经放弃了，因为它应该有用。我不知道这是 discord.js 错误还是什么，但我找不到问题出在哪里。

const Discord = require('discord.js');
const live = "";
const rmke = "";

module.exports.run = async(bot, message, args) => {
  let msg = await message.channel.send("Vote! LIVE  RMK ");

  await msg.react(live);
  await msg.react(rmke);

  const reactions = await msg.awaitReactions(reaction => reaction.emoji.name === live || reaction.emoji.name === rmke, {
    time: 15000
  });
  let embed = new Discord.RichEmbed()
    .setTitle("Ready")
    .setDescription("Results")
    .addField("LIVE!", `${live}: ${reactions.get(live).count -1 }`)
    .addField("RMK!", `${rmke}: ${reactions.get(rmke).count -1 }`);
  message.channel.send({
    embed: embed
  });
}

module.exports.help = {
  name: "vta"
}

如果没有人做出反应，reactions.get(live) 和 reactions.get(rmke) 将是未定义的，因为您的机器人在 awaitReactions 之前做出反应，因此不会被计算在内。

处理此问题的最简单方法是：

reactions.get(live) ? reactions.get(live).count : 0
