如何查看用户是否具有存储在变量中的角色？

Question

我正在为我的机器人创建角色分配命令，因此用户可以键入 h.addrole @user @role 如果用户具有角色，我正在尝试创建它，它会输出说 This user already has this role! 每当我尝试使用该命令时，它总是输出
(node:5224) UnhandledPromiseRejectionWarning: TypeError: userToModify.hasRole is not a function
我的代码如下：

} if (message.content.startsWith(config.prefix + "addrole")) {
  let userToModify = message.mentions.members.first();
  let roleToAdd = message.mentions.roles.first();
  if (userToModify.hasRole(roleToAdd)) return message.channel.send("This user already has this role!")
  if (!args) return message.channel.send("Please enter a mentioned user and a mentioned role to assign (e.g h.addrole @Brickman @Moderator")
  if (!message.member.hasPermission("MANAGE_ROLES")) return message.channel.send("You do not have permission for this!")
  userToModify.addRole(roleToAdd); 
  return message.channel.send("Succesfully added role " + roleToAdd + " to member " + userToModify + "!");

就像它说的那样...hasRole 不是函数。

改为这样尝试： if (userToModify.has(roleToAdd.id)) return message.channel.send("This user already has this role!")
