Discord.js v14 TypeError: (intermediate value).setColor不是函数求助

错误原因 #

Discord.js v14及以上版本中，嵌入消息的构造类是EmbedBuilder，而非你代码里的Embed。使用错误的类实例化对象后，对象不存在setColor这类方法，因此抛出类型错误。

修复步骤 #

1. 修正导入语句，替换为正确的类名：

const { EmbedBuilder } = require("discord.js");

2. 将实例化嵌入对象的代码中的new Embed()改为new EmbedBuilder()，其余链式调用逻辑保持不变：

const embed = new EmbedBuilder()
  .setColor("#FF0000")
  .setTitle("🏓 Pong!")
  .setDescription(`Latency : ${client.ws.ping}ms`)
  .setTimestamp()
  .setFooter({ text: `Requested by ${interaction.user.tag}`, iconURL: `${interaction.user.displayAvatarURL()}` });

3. （可选优化）如果你的斜杠命令没有提前延迟回复，建议将interaction.followUp改为interaction.reply，避免触发交互超时错误：

interaction.reply({ embeds: [embed] });

修复后的完整代码 #

const { EmbedBuilder } = require("discord.js");

module.exports = {
  name: "ping",
  description: "Returns websocket latency",

  run: async (client, interaction) => {
    const embed = new EmbedBuilder()
      .setColor("#FF0000")
      .setTitle("🏓 Pong!")
      .setDescription(`Latency : ${client.ws.ping}ms`)
      .setTimestamp()
      .setFooter({ text: `Requested by ${interaction.user.tag}`, iconURL: `${interaction.user.displayAvatarURL()}` });
    interaction.reply({ embeds: [embed] });
  },
};
