TypeError: Cannot read property 'has' of undefined /

Question

所以，我正在为我的Discord服务器创建一个bot。我得到了这个错误。请记住我是一个业余爱好者:)。提前感谢，非常感谢^^。

const config = require('../config.js');
module.exports = message => {
let client = message.client;
if (message.author.bot) return;
if (!message.content.startsWith(config.prefix)) return;
let command = message.content.split(' ')[0].slice(config.prefix.length);
let params = message.content.split(' ').slice(1);
let cmd;
if (client.commands.has(command)) {
cmd = client.commands.get(command);
} else if (client.aliases.has(command)) {
cmd = client.commands.get(client.aliases.get(command));
};
if (cmd) {
if(!message.guild) {
if(cmd.config.guildOnly === true) {
return;
};
};
if (cmd.config.permLevel) {
if(cmd.config.permLevel === "BOT_OWNER") {
if(!config.geliştiriciler.includes(message.author.id)) {
message.channel.send(`Bu komutu kullanabilmek için `${cmd.config.permLevel}` yetkisine sahip olmalısın.`).then(msg => msg.delete({timeout: 3000}));
return;
}
}
if(!message.member.hasPermission(cmd.config.permLevel)) {
message.channel.send(`Bu komutu kullanabilmek için `${cmd.config.permLevel}` yetkisine sahip olmalısın.`).then(msg => msg.delete({timeout: 3000}));
return;
};
};
cmd.run(client, message, params);
};
};

Answer 1

添加一些布尔值用于检查client.commands/client.aliases是否未定义

if (client.commands && client.commands.has(command)) {
cmd = client.commands.get(command);
} else if (client.aliases && client.aliases.has(command)) {
cmd = client.commands.get(client.aliases.get(command));
};

在第7行，请试试这个

const cmd =
message.client.commands.get(command) ||
message.client.commands.find(
(cmd) => cmd.aliases && cmd.aliases.includes(command) // if you're also using aliases
);
if (!command) return;
