我有一个错误，我无法解决错误是标题我已经在其他情况下进行了测试

    <ion-icon class="liked" (click)="toggleLikeState(feed);$event.stopPropagation();"
        tappable name="{{feed.IsLike ? 'heart' : 'heart-empty'}}">
    </ion-icon>

   toggleLikeStates(feed: Feed) {
    this.storage.get('userID').then(async (loggedinUId) => {
      const value: UserLikedPost = {
        LoginUserId: loggedinUId,
        UserId: UserId,
        PostId: PostId
      };

      this.apiService.postLike(value).then(
        async (success) => {
          console.log("success", success);
          feed.IsLike = !feed.IsLike;
          feed.IsLike ? feed.LikesCount++ : feed.LikesCount--;
        }, (error) => {
          console.log("Error", error);
        });
    });

齿轮中的命令仍然是齿轮实例的方法。传递给他们的第一个参数始终是实例

class utility(commands.Cog):

    def __init__(self, client):
        self.client = client

    @commands.Cog.listener()
    async def on_ready(self):
        print("Cog utility pronto!")

    @commands.command()
    async def ping(self, ctx):
        await ctx.send(f"Pong! {round(self.client.latency * 1000)}ms")

    @commands.command()
    async def clear(self, ctx, amount=5):
        await ctx.channel.purge(limit=amount)
        await ctx.send(f"{amount}Messaggi eliminati")

discord.ext.commands.errors.CommandInvokeError：命令引发了一个异常：AttributeError：'utility'对象没有属性'channel'
