【问题描述】：

我在尝试工作箱和角度时遇到了一个奇怪的错误。

一直在关注工作箱中的指南和文档，也一直在寻找答案，但找不到任何适合我的解决方案。

无论如何，我得到了这个错误

错误：在您的软件源中找不到 self.__WB_MANIFEST。

当我使用此代码创建 service-worker.js 时

service-worker.js

import  precacheAndRoute  from "workbox-precaching";
import  registerRoute  from "workbox-routing";
import  StaleWhileRevalidate  from "workbox-strategies";
import  BroadcastUpdatePlugin  from "workbox-broadcast-update";

// Use with precache injection
precacheAndRoute(self.__WB_MANIFEST);

registerRoute(
  ( url ) => url.pathname.startsWith("/"),
  new StaleWhileRevalidate(
    plugins: [new BroadcastUpdatePlugin()],
  )
);

但如果我注释掉 StaleWhileRevalidate 的导入，它会起作用。

import  precacheAndRoute  from "workbox-precaching";
import  registerRoute  from "workbox-routing";
// import  StaleWhileRevalidate  from "workbox-strategies";
import  BroadcastUpdatePlugin  from "workbox-broadcast-update";

// Use with precache injection
precacheAndRoute(self.__WB_MANIFEST);

registerRoute(
  ( url ) => url.pathname.startsWith("/"),
  new StaleWhileRevalidate(
    plugins: [new BroadcastUpdatePlugin()],
  )
);

有人知道为什么会这样吗？

我将采用inject manifest 方法。

webpack.config.js

const  InjectManifest  = require("workbox-webpack-plugin");

module.exports = 
  // Other webpack config...
  plugins: [
    // Other plugins...
    new InjectManifest(
      swSrc: "./src/service-worker.js",
    ),
  ],
;

【参考方案1】：

最后我解决了，@angular-builders/custom-webpack 和 @angular-devkit/build-angular 之间的版本差异似乎破坏了构建。也许它会帮助别人。

“开发依赖”： "@angular-builders/custom-webpack": "^12.1.2", "@angular-devkit/build-angular": "~12.2.5", "@angular-devkit/build-angular": "~12.1.2", ...
