我试图在服务器上使角色计数，但我不知道如何获取角色计数

Question

我是新手，我尝试使角色计数： 我试过这个：

const RolesChannel = client.channels.get("649537269988065280")
RolesChannel.setName(RolesChannel.guild.Roles + ' Roles!')
console.log('updated ' + RolesChannel.guild.name+ ''s Roles channel!')

它会将通道命名为：未定义的角色！

然后我尝试了：

const RolesChannel = client.channels.get("649537269988065280")
RolesChannel.setName(RolesChannel.guild.Roles.size + ' Roles!')
console.log('updated ' + RolesChannel.guild.name+ ''s Roles channel!')

它只会崩溃并显示以下错误消息：

TypeError: Cannot read property 'size' of undefined

我不明白为什么当角色是公会的属性时，你试图从频道中获取角色的数量。 如果这是你需要的，那么只需获取公会ID并获取该公会中角色的大小。

let guild = clients.guilds.get("Guild id");
Console.log(guild.roles.size);
