ServiceWorker不更新缓存

我正在尝试安装一个 ServiceWorker

我有 index.html v0.0.1 缓存,如果缓存版本更改为 v0.0.2 或者其他任何东西,它应该重新下载 index.html

我把行李装上 与:

if('serviceWorker' in navigator){
    navigator.serviceWorker
        .register('serviceWorker.js')
        .then(() => { 
            console.log('Service Worker Registered');
        });
}

以下是:

serviceWorker.js

const currentVersion = 'v0.0.1';

self.addEventListener('install', e => {
    e.waitUntil(
        caches.open(currentVersion).then(cache => cache.addAll([
            '',
            'index.html',
            'js/load.min.js',
            'lib/db.js/js/db.min.js'
        ]))
    );
});

self.addEventListener('fetch', e => {
    e.respondWith(
        caches.match(e.request).then(resp => {
            return resp || fetch(e.request).then(response => {
                return caches.open(currentVersion).then(cache => {
                    cache.put(e.request, response.clone());
                    return response;
                });  
            });
        })
    );
});

self.addEventListener('activate', e => {
    e.waitUntil(
        caches.keys().then(keyList => 
            Promise.all(keyList.map(key => key != currentVersion ? caches.delete(key) : Promise.resolve()))
        )
    );
});

但我试过编辑 index.html 以及更新 serviceWorker index.html

我做错了什么?
