除了已经给出的正确答案之外，如果你还想删除SW缓存，你可以调用以下方法:

if ('caches' in window) {
    caches.keys()
      .then(function(keyList) {
          return Promise.all(keyList.map(function(key) {
              return caches.delete(key);
          }));
      })
}

另一种可能是通过浏览器访问“缓存存储”部分，然后点击“清除站点数据”按钮:

安全卸载Service Worker

if ('serviceWorker' in navigator) {
      navigator.serviceWorker.getRegistrations().then(function (registrations) {
        for (const registration of registrations) {
          // unregister service worker
          console.log('serviceWorker unregistered');
          registration.unregister();
        }
      });
    }

检测service worker:

navigator.serviceWorker.controller

删除service worker的代码:

navigator.serviceWorker.getRegistrations()
  .then(registrations => {
    registrations.forEach(registration => {
      registration.unregister();
    })
  });

  navigator.serviceWorker.getRegistrations().then(function(registrations) {
   for(let registration of registrations) {
    registration.unregister()
  } })

  if(window.navigator && navigator.serviceWorker) {
    navigator.serviceWorker.getRegistrations()
    .then(function(registrations) {
      for(let registration of registrations) {
        registration.unregister();
      }
    });
  }

  if ('caches' in window) {
      caches.keys()
        .then(function(keyList) {
            return Promise.all(keyList.map(function(key) {
                return caches.delete(key);
            }));
        })
  }

  if ('serviceWorker' in navigator) {
        navigator.serviceWorker.getRegistrations().then(function (registrations) {
          for (const registration of registrations) {
            // unregister service worker
            console.log('serviceWorker unregistered');
            registration.unregister();

            setTimeout(function(){
              console.log('trying redirect do');
              window.location.replace(window.location.href); // because without redirecting, first time on page load: still service worker will be available
            }, 3000);
          }
        });
      }

它也可以在Chrome通过应用程序选项卡:

如果你的服务人员不让你更新文件。你需要用下面的代码替换serviceworker文件(sw.js / serviceworker .js):

self.addEventListener('install', function(e) {
  self.skipWaiting();
});

self.addEventListener('activate', function(e) {
  self.registration.unregister()
    .then(function() {
      return self.clients.matchAll();
    })
    .then(function(clients) {
      clients.forEach(client => client.navigate(client.url))
    });
});

仅供参考，如果你使用的是MacOS Safari浏览器，有一种方法可以强制注销service worker (Safari 12.1的步骤和图片):

Safari >首选项…>隐私>管理网站数据… 输入域名(例如。'localhost')，点击“删除”

注意:除了service worker之外，这还将删除该域的所有缓存、cookie和数据库。
