Question

我正在制作一个Angular渐进式应用程序。我正在与服务工作者一起工作并在CLI上出错 -

Error: Expected to find an ngsw-config.json configuration file in the /home/nancy/Desktop/beautyOfSoul folder. Either provide one or disable Service Worker in your angular.json configuration file.

我正在处理Angular 6.我知道，angular.json文件应该包含"serviceWorker": true但我在angular.json文件中找不到任何类似的内容，我可以在其中编写"serviceWorker": true。

{ 
  "apps": [{ 
    ..., 
    "serviceWorker": true
  }]
}

我的angular.json文件如下：

Here is the official doc。您可以运行以下命令，该命令将设置将您的应用程序转换为PWA所需的文件和库。

ng add  @angular/pwa --project *project-name*

运行此命令时，除了配置文件更改和安装库之外，

1）它会在＆＃34; src＆＃34; 文件夹下（不在资源中）添加 manifest.json，最好将其保留为默认方式，尽管您可以尝试映射它从那里。

2）它会在项目的根目录（src的父目录）中添加 ngsw-config.json。这必须在这个位置从Angular 6开始（在5中，它在src中我猜它在6中被更改为根文件夹）在你的情况下找不到这个文件导致了这个问题。要么在这里移动现有的一个，要么删除现有的一个，让上面的一个为你创建它（这是更好的）。

无法在角度js中配置服务工作者
