我试图在服务器上进行角色计数，但我不知道如何获取角色计数

Question

我对此很陌生，我尝试计算角色： 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!')

它会将频道命名为：undefined Roles！

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!')

它会因为这个错误消息而崩溃：

TypeError: Cannot read property 'size' of undefined

当角色是公会的财产时，我不明白您为什么要尝试从频道中获取角色的计数。 如果这是您需要的，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);
