运行node index.js load时遇DiscordAPIError[50035]重复命令名错误求助

代码与错误信息 #

我的index.js代码：

const LOAD_SLASH = process.argv[2] == "load"

const CLIENT_ID = "981858607362629663"
const GUILD_ID = "970702726348546078"

const client = new Client({
    intents: [
        GatewayIntentBits.Guilds,
        GatewayIntentBits.GuildMessages,
        GatewayIntentBits.MessageContent,
        GatewayIntentBits.GuildMembers,
        GatewayIntentBits.GuildVoiceStates
    ]
})

client.slashcommands = new Discord.Collection()
client.player = new Player(client, {
    ytdlOptions: {
        quality: "highestaudio",
        highWaterMark: 1 << 25
    }
})

let commands = []

const slashFiles = fs.readdirSync("./slash").filter(file => file.endsWith(".js"))
for (const file of slashFiles){
    const slashcmd = require(`./slash/${file}`)
    client.slashcommands.set(slashcmd.data.name, slashcmd)
    if (LOAD_SLASH) commands.push(slashcmd.data.toJSON())
}

执行node index.js load后报错：

DiscordAPIError[50035]: Invalid Form Body 5[APPLICATION_COMMANDS_DUPLICATE_NAME]: Application command names must be unique at SequentialHandler.runRequest

已尝试卸载重装discord.js，问题未解决。

• 排查命令名称重复：检查./slash目录下所有命令文件，确保每个命令的data.name完全唯一。注意Discord命令名称不区分大小写，Play和play会被判定为重复。
• 添加加载时去重逻辑：修改命令加载循环，跳过重复名称的命令，避免生成重复的命令数组：

  const slashFiles = fs.readdirSync("./slash").filter(file => file.endsWith(".js"))
  const commandNames = new Set()
  let commands = []
  
  for (const file of slashFiles){
      const slashcmd = require(`./slash/${file}`)
      const cmdName = slashcmd.data.name
      
      if (commandNames.has(cmdName)) {
          console.warn(`发现重复命令：${cmdName}（文件：${file}），已跳过`)
          continue
      }
      
      commandNames.add(cmdName)
      client.slashcommands.set(cmdName, slashcmd)
      if (LOAD_SLASH) commands.push(slashcmd.data.toJSON())
  }
  

• 清理现有命令：如果是服务器专属命令，可先清空服务器内已存在的命令，再重新提交新命令，避免与旧命令冲突：

  if (LOAD_SLASH) {
      const { REST, Routes } = require('discord.js');
      const rest = new REST({ version: '10' }).setToken(process.env.DISCORD_TOKEN);
  
      // 清空服务器现有命令
      await rest.put(
          Routes.applicationGuildCommands(CLIENT_ID, GUILD_ID),
          { body: [] }
      );
  
      // 提交新命令
      await rest.put(
          Routes.applicationGuildCommands(CLIENT_ID, GUILD_ID),
          { body: commands }
      );
  }
  

• 检查重复文件：确认./slash目录下没有重复的命令文件（如play.js和play_副本.js但内部命令名称一致）。
