Question

说实话，我需要帮助，因为我已经放弃了，因为它应该起作用。我不知道这是discord.js错误还是其他原因，但我找不到问题所在。

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)，并且reactions.get(rmke)将是不确定的，因为您的机器人在awaitReactions之前做出了反应，因此不会被计算在内。

最简单的解决方法是：

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

奇怪的“计数属性未定义”
