注入 'service-worker.js' 的脚本路径应该在根目录吧。

如果是类似 https://blogs.kainy.cn/2018/07/%E5%8D%9A%E5%AE%A2%EF%BC%8F%E8%B5%84%E8%AE%AF%E7%B1%BB%E7%BD%91%E9%A1%B5%E5%9C%A8%E5%B0%8F%E7%A8%8B%E5%BA%8F%E4%B8%AD%E5%88%86%E4%BA%AB%E7%9A%84%E6%96%B9%E6%A1%88/ 的URL结构，就会导致访问不到sw.js文件。

Hi kainy, the sw.js should only be registered once at top-level entry page (for best practice, see here) and it will send all files to the service-worker. That is to say, it is ok for any subpage not reading sw.js register as long as the sw.js have been invoked at the entry page of your website.
