Checking whether a channel exists or has a duplicate - TypeError: fn.bind is not a function

Question

我正在尝试在 Discord.js v12 中创建私人频道。我的代码如下：

const name = msg.author.tag;

        const everyoneRole = msg.guild.roles.everyone;

        if (msg.guild.channels.cache.find('name', name)) { //checks if there in an item in the channels collection that corresponds with the supplied parameters, returns a boolean
            msg.reply(`You already have a channel`).catch(console.error);
            return; //prevents the rest of the code from being executed
        }

        msg.guild.channels.create(msg.author.username, {type: 'category'})
            .then(parent =>
                Promise.all([

                    msg.guild.channels.create(name, {type: 'text', parent}).then(r => {
                        r.updateOverwrite(msg.author.id, { VIEW_CHANNEL: true });
                        r.updateOverwrite(everyoneRole, { VIEW_CHANNEL: false });
                    }),

                    msg.guild.channels.create(name, {type: 'voice', parent}).then(r => {
                        r.updateOverwrite(msg.author.id, { VIEW_CHANNEL: true });
                        r.updateOverwrite(everyoneRole, { VIEW_CHANNEL: false });
                    }),

                ])
            )

        const success = new Discord.MessageEmbed()
            .setDescription(`Created, please see bottom of the server`)
        await msg.channel.send(success).then(msg => msg.delete({timeout: 5000})).catch(O_o => {});

我正在检查频道是否存在。当我尝试使用名称 bot returns 查找频道时，我如下所示：

An error occurred while running the command: TypeError: fn.bind is not a function
You shouldn't ever receive an error like this.

我看过这些帖子：

TypeError: fn.bind is not a function

Way to check if a channel exists

但是大部分都没有解决我的问题。

我正在使用 Discord.js v12

您的问题与您对 .find() 方法的使用有关。有了v12，方法变了（查看here）。

您需要更换：

msg.guild.channels.cache.find('name', name)

作者：

msg.guild.channels.cache.find(channel => channel.name === name);
