Lyrics命令代码如下：

const { EmbedBuilder, ApplicationCommandOptionType } = require("discord.js");
const { get } = require("node-superfetch");
const config = require("../config.js");
const db = require("../mongoDB");

module.exports = {
  name: "lyrics",
  description: "Gets the lyrics of a song.",
  userPerms: [],
  player: true,
  dj: false,
  inVoiceChannel: true,
  sameVoiceChannel: true,
  options: [
    {
      name: "song",
      description: "Song name to return lyrics for.",
      type: ApplicationCommandOptionType.String,
      required: false,
    },
  ],

  /**
   *
   * @param {Client} client
   * @param {CommandInteraction} interaction
   */

 run: async (client, interaction) => {
    await interaction.reply({
      embeds: [
        new EmbedBuilder()
          .setColor(client.embedColor)
          .setDescription("🔎 **Searching...**"),
      ],
    });

    let player;
    if (client.manager) {
      player = client.manager.players.get(interaction.guild.id);
    } else {
      return interaction.reply({
        embeds: [
          new EmbedBuilder()
            .setColor("Red")
            .setDescription("Node not connected"),
        ],
      });
    }

    const args = interaction.options.getString("song");
    if (!args && !player) {
      return interaction.editReply({
        embeds: [
          new EmbedBuilder()
            .setColor("Red")
            .setDescription("There's no music playing."),
        ],
      });
    }

    let search = args ? args : player.queue.current.title;
    let url = `https://api.darrennathanael.com/lyrics?song=${search}`;

    let lyrics = await get(url);

    if (!lyrics || lyrics.status !== 200) {
      return interaction.editReply({
        embeds: [
          new EmbedBuilder()
            .setColor("Red")
            .setDescription(
              `❌ | No lyrics found for ${search}!\nMake sure you entered your search correctly.`
            ),
        ],
      });
    }

    let text = lyrics.body.lyrics;
    let lyricsEmbed = new EmbedBuilder()
      .setColor(client.embedColor)
      .setTitle(`${lyrics.body.full_title}`)
      .setURL(lyrics.url)
      .setThumbnail(lyrics.body.thumbnail)
      .setDescription(text);

    if (text.length > 4096) {
      text = text.substring(0, 4090) + "[...]";
      lyricsEmbed
        .setDescription(text)
        .setFooter({ text: "Truncated, the lyrics were too long." });
    }

    return await interaction.editReply({ embeds: [lyricsEmbed] });
  },
};

已尝试给new EmbedBuilder添加const关键字，问题未解决。

错误核心是client.embedColor的值为undefined，而EmbedBuilder.setColor()要求传入合法的颜色值（十六进制字符串、十进制数字、RGB数组或预定义颜色名），传入undefined会触发参数验证失败。

可以通过以下两种方式解决：

• 方法一：确保client.embedColor已正确配置
  在机器人主文件或配置文件中，给client.embedColor赋值合法颜色值，示例：

  // 初始化client后设置
  client.embedColor = "#2F3136"; // 十六进制颜色
  // 或
  client.embedColor = 0x2F3136; // 十进制颜色
  

• 方法二：添加默认值兜底
  修改代码中两处setColor(client.embedColor)为：

  .setColor(client.embedColor || "#2F3136")
  

  这样当client.embedColor不存在时，会自动使用预设的默认颜色。
