Question

我有一个欢迎消息机器人，每次有人加入时都会发送欢迎消息，但有时会在控制台中引发错误，提示：

    member.guild.channels.cache.find(ch => ch.name === "・????").send(exampleEmbed).catch(e => co    nsole.error(`Welcome Error in ${message.guild.name}`) | message.channel.send("__**ERROR:**__ ** Someone joined the server but I was 
le to catch it.**"));
                                                                   ^

TypeError: Cannot read property 'send' of undefined

代码：

client.on('guildMemberAdd', member => {


    const exampleEmbed = new Discord.MessageEmbed()
        .setColor('RANDOM')
        .setTitle(`Welcome to lovell <$, **${member.user.username}**`)
        .setImage('https://images-ext-1.discordapp.net/external/Gy-micqoX7qrlivnytbmFgfTbxPx_CSvgChFLE3qC7g/https/media.discordapp.net/attachments/755425128635957348/758525058934767617/HaxzUWa46sK5CXKzIR.gif')
        .setFooter('Boost Us');

    member.guild.channels.cache.find(ch => ch.name === "・????").send(exampleEmbed).catch(e => console.error(`Welcome Error in ${message.guild.name}`) | message.channel.send("__**ERROR:**__ ** Someone joined the server but I was unable to catch it.**"));
})

我该如何解决？

Answer 1

有一种更简单的方法可以执行您要执行的操作。复制该频道的ID，然后像这样在您的代码中获取该频道：

bot.on('guildMemberAdd', (member) => {
    const channel = member.guild.channels.cache.get('channel-id');
    channel.send('Welcome');
});

Answer 2

我的猜测是，如果找不到频道，则会发生该错误。找不到的通道将返回未定义的。 DiscordJS website中的这段代码将检查通道是否存在，如果不存在，则不会运行该函数的其余部分。

也许尝试一下？：

client.on('guildMemberAdd', member => {
    
    let welChannel = member.guild.channels.cache.find(ch => ch.name === "・????")

    const exampleEmbed = new Discord.MessageEmbed()
        .setColor('RANDOM')
        .setTitle(`Welcome to lovell <$, **${member.user.username}**`)
        .setImage('https://images-ext-1.discordapp.net/external/Gy-micqoX7qrlivnytbmFgfTbxPx_CSvgChFLE3qC7g/https/media.discordapp.net/attachments/755425128635957348/758525058934767617/HaxzUWa46sK5CXKzIR.gif')
        .setFooter('Boost Us');

    welChannel.send(exampleEmbed).catch(e => console.error(`Welcome Error in ${message.guild.name}`) | message.channel.send("__**ERROR:**__ ** Someone joined the server but I was unable to catch it.**"));
})

如果这不起作用，则可能是该漫游器找不到・????频道。
