Discord.js斜杠命令报错：Cannot access 'DurationFormatter' before initialization

问题根因 #

你的代码第3行存在两处逻辑错误，直接触发了报错：

1. 未提前导入DurationFormatter类就直接尝试实例化
2. 错误使用解构赋值接收类实例的返回值，导致变量初始化顺序异常

修复步骤 #

1. 先安装对应的依赖包（如果尚未安装）：

npm install @discordjs/formatters

2. 修改头部的导入和初始化代码：
   将原代码第3行：

const { DurationFormatter } = new DurationFormatter();

替换为：

// 先从依赖包导入DurationFormatter类
const { DurationFormatter } = require("@discordjs/formatters");
// 实例化 formatter 工具
const durationFormatter = new DurationFormatter();

3. 修改run方法内的调用逻辑，将：

const duration = DurationFormatter.format(client.uptime);

替换为：

const duration = durationFormatter.format(client.uptime);

修正后完整代码 #

const { version } = require("discord.js");
const { codeBlock } = require("@discordjs/builders");
const { DurationFormatter } = require("@discordjs/formatters");
const durationFormatter = new DurationFormatter();

exports.run = async (client, interaction) => {
  const duration = durationFormatter.format(client.uptime);
  const stats = codeBlock("asciidoc", `= STATISTICS =
• Men Usage   :: ${(process.memoryUsage().heapUsed / 1024 / 1024).toFixed(2)}
• Uptime      :: ${duration}
• Users       :: ${client.guilds.cache.map(g => g.memberCount).reduce((a, b) => a + b).toLocaleString()}
• Servers     :: ${client.guilds.cache.size.toLocaleString()}
• Channels    :: ${client.channels.cache.size.toLocaleString()}
• Discord.js  :: v${version}
• Node        :: ${process.version}`);
  await interaction.reply(stats);
};

exports.commandData = {
  name: "stats",
  description: "Show's the bots stats",
  options: [],
  defaultPermissions: true,
};

exports.guildOnly = false;
