roles.cache给出TypeError：无法读取未定义的属性'id'

Question

[当我尝试执行member.roles.cache时，我总是得到TypeError: Cannot read property 'id' of undefined

当我console.log（member.role）我得到：

GuildMemberRoleManager {member: GuildMember, guild: Guild, client: Client}
_roles:TypeError: Cannot read property 'id' of undefined
cache:TypeError: Cannot read property 'id' of undefined
client:Client {_events: Object, _eventsCount: 2, _maxListeners: undefined, …}
color:TypeError: Cannot read property 'id' of undefined
guild:Guild {members: GuildMemberManager, channels: GuildChannelManager, roles: RoleManager, …}
highest:TypeError: Cannot read property 'id' of undefined
hoist:TypeError: Cannot read property 'id' of undefined
member:GuildMember {guild: Guild, user: User, joinedTimestamp: 1589586365337, …}

我不知道发生了什么

提前感谢：）

[如果您要查看成员是否具有特定角色（问题尚不明确），请尝试使用member.roles.cache.some(role => role.name === 'role_name')。希望这会有所帮助：）
