discord.js的fn.bind错误代码是什么? [英] What is the fn.bind Error code for discord.js?

问题描述

我正在尝试创建一个可以给您提供命令的命令！role {pronoun}.如果代词存在，它将为您提供现有角色，但如果代词不存在，它将为您提供已经扮演的角色.每次我运行命令时，都会收到一条错误消息，提示类型错误:fn.bind不是函数".我不知道为什么，如果你们所有人都能帮助我，那真是太好了.

I'm trying to make a command that gives you on the command, !role {pronoun}. If the pronoun exists then it will give you the existing role, but if it doesn't exist it will give you the role already made. Each time I run the command though I get an error that says "Type Error: fn.bind is not a function". I have no clue why, if y'all could help me out that would be amazing.

client.on('message', async message => {
        var input = (message.content.substr(12))
        var roleName = (message.content.substr(12));
        var role = message.guild.roles.cache.find(r => r.name == roleName);
        if(!role){
            if (message.member.roles.cache.find("name", "Member")){ 
            message.channel.sendMessage('Sorry you already have a pronoun');
            return;
            }
            else if (input === ""){
            message.channel.sendMessage('Please Enter a Valid Pronoun Name');
            return;
            }
            else{
            var pronounName = message.guild.roles.find(role => role.name === "Member");
            message.member.guild.createRole({
                name: message.content.substr(12),
        }).then(function(role)
        {
            message.member.addRole(role);
            message.member.addRole(pronounName);
            message.channel.sendMessage('You have created the pronoun: ' + role);
        });
            }   
        }else{
            message.channel.sendMessage('That Pronoun Already Exists!');
            return;
        }
    })

推荐答案

这是由 message.member.roles.cache.find("name"，"Member")引起的. .find()方法接受一个函数作为其第一个参数(您提供了一个字符串)，并将用作 this 的值作为其第二个参数(您提供了另一个字符串).

It's caused by message.member.roles.cache.find("name", "Member"). The .find() method accepts a function as its first argument (you provided a string) and the value to use as this as its second argument (you provided another string).

您可以通过检查 name 属性是否等于"Member" :

You could find a role by checking if the name property is equal to "Member":

message.member.roles.cache.find((role) => role.name === 'Member')

PS:您的代码中可能还有其他错误，但是 TypeError:fn.bind不是函数可以解决此问题.

PS: Chances are there are other errors in your code but TypeError: fn.bind is not a function can be solved by this.
