Discord.js buyship命令出现ValidationError：期望值不为数组

我尝试实现一个功能，列出船只名称及其价格供用户选择购买，但对应的Discord.js buyship命令无法正常运行，始终输出错误：ValidationError: Expected the value to not be an array。

相关代码：

const { SlashCommandBuilder } = require('discord.js');
const { getUserById, updateUserById } = require('../utils/user');

module.exports = {
    data: new SlashCommandBuilder()
        .setName('buyship')
        .setDescription('Buy a ship from the shop')
        .addStringOption(option =>
            option.setName('ship')
                .setDescription('Select the ship you want to buy')
                .setRequired(true)
                .addChoices([{ name: 'Sloop', value: 'sloop' }, { name: 'Frigate', value: 'frigate' }, { name: 'Galleon', value: 'galleon' }, { name: "Man o' war", value: 'manowar'}])),
   
    async execute(interaction) {
        const ship = interaction.options.getString('ship');
        const shipPrices = {
            sloop: 100,
            frigate: 250,
            galleon: 500,
            manowar: 1000
        };
        const user = await getUserById(interaction.user.id);
        const balance = user.balance;
        const price = shipPrices[ship];
        if (!price) {
            return interaction.reply({ content: 'That is not a valid ship.', ephemeral: true });
        }
        if (balance < price) {
            return interaction.reply({ content: 'You do not have enough money to buy this ship.', ephemeral: true });
        }
        const newBalance = balance - price;
        await updateUserById(interaction.user.id, { balance: newBalance, ship: ship });
        return interaction.reply(`You bought a ${ship} for ${price} coins.`);
    },
};

报错的核心原因是addChoices方法的调用方式错误。你当前是把包含多个选项的数组直接传给addChoices，但在Discord.js v14及以上版本中，addChoices需要逐个传入选项对象，或者使用扩展运算符展开数组，而不是直接传递整个数组。

修改后的代码（重点修改addChoices部分）：

const { SlashCommandBuilder } = require('discord.js');
const { getUserById, updateUserById } = require('../utils/user');

module.exports = {
    data: new SlashCommandBuilder()
        .setName('buyship')
        .setDescription('Buy a ship from the shop')
        .addStringOption(option =>
            option.setName('ship')
                .setDescription('Select the ship you want to buy')
                .setRequired(true)
                // 方法一：逐个传入选项对象
                .addChoices(
                    { name: 'Sloop', value: 'sloop' },
                    { name: 'Frigate', value: 'frigate' },
                    { name: 'Galleon', value: 'galleon' },
                    { name: "Man o' war", value: 'manowar' }
                )
                // 方法二：使用扩展运算符展开数组
                // .addChoices(...[{ name: 'Sloop', value: 'sloop' }, { name: 'Frigate', value: 'frigate' }, { name: 'Galleon', value: 'galleon' }, { name: "Man o' war", value: 'manowar'}])
        ),
   
    async execute(interaction) {
        const ship = interaction.options.getString('ship');
        const shipPrices = {
            sloop: 100,
            frigate: 250,
            galleon: 500,
            manowar: 1000
        };
        const user = await getUserById(interaction.user.id);
        const balance = user.balance;
        const price = shipPrices[ship];
        if (!price) {
            return interaction.reply({ content: 'That is not a valid ship.', ephemeral: true });
        }
        if (balance < price) {
            return interaction.reply({ content: 'You do not have enough money to buy this ship.', ephemeral: true });
        }
        const newBalance = balance - price;
        await updateUserById(interaction.user.id, { balance: newBalance, ship: ship });
        return interaction.reply(`You bought a ${ship} for ${price} coins.`);
    },
};

这样修改后，addChoices就能正确识别每个选项对象，不会把整个数组当成单个参数处理，也就不会触发"Expected the value to not be an array"的验证错误。
