使用service worker时看不到对静态文件所做的更改

我已经为reactjs应用程序注册了一名服务人员。 activate 事件被调用,我可以更新服务工作线程

这是 事件侦听器

self.addEventListener('activate', event => {
const expectedCacheNames = Object.values(CURRENT_CACHES);
event.waitUntil(
    caches.keys().then(cacheNames => { 
        return Promise.all(
            cacheNames.map(cacheName => {
                if(!expectedCacheNames.includes(cacheName)) {
                    console.log('Deleting out of date cache: ', cacheName);
                    return caches.delete(cacheName);
                }
            })
        )
    })
   )
});

这个问题是特定的反应吗?

代码结构如下

/src
  /components
  index.js //this is where I register service worker after calling ReactDOM
/public
  sw.js
  //other assests ...
