能否更新一下依赖的 lru-cache 版本

当前版本 [email protected]，仓库里面依赖的是 4.1.1

https://github.com/isaacs/node-lru-cache/blob/main/CHANGELOG.md#1020

这个插件还能用吗？

我看都是5年前的提交，请问还能用吗

看起来已经不能再ts里用了

类型“Application”上不存在属性“lru”。ts(2339)

import { provide, inject, Context } from '@ali/midway'

@provide('cacheService')
export class CacheService{
  @inject()
  ctx: Context;

  get(key: string) {
    return this.ctx.app.lru.get(key)
  }

  set(key: string, value) {
    return this.ctx.app.lru.set(key, value)
  }
}
