在 Angular 8 中使用 cli 命令添加 Web Worker 后出现错误 [英] Getting error after adding web worker with cli command in Angular 8

问题描述

Angular 8 为网络工作者添加了更好的支持.我没有运气让它工作.有人知道我做错了什么吗?

Angular 8 has added a better support for web workers. I had no luck to get it working. Does someone know what am i doing wrong?

这是我遵循的官方指南.

使用这个 cli 命令，我生成了 web worker:

With this cli command i generated web worker:

ng generate webWorker my-worker

cli 生成了 my-worker.worker.ts 文件和 tsconfig.worker.json 文件，并更新了以下文件:angular.json、tsconfig.app.json.

cli has generated my-worker.worker.ts file and tsconfig.worker.json file, and updated following files: angular.json, tsconfig.app.json.

在此之后我收到以下错误:

After this im getting following error:

推荐答案

我也有这个问题，并注意到在一个新的 Angular 8 项目中，所有 tsconfig.*.json 文件都在根目录，只有根tslint.json文件.

I had this issue too, and noticed that in a new Angular 8 project, all tsconfig.*.json files are in the root directory, and there is only the root tslint.json file.

这是我所做的:

• 将 tslint.json、tsconfig.app.json 和 tsconfig.spec.json 从新生成的 CLI 8 项目复制到我的项目根目录.
• 从 src 中删除了 tslint.json、tsconfig.app.json 和 tsconfig.spec.json> 目录.
• 编辑 angular.json 中的 tsConfig 值以在项目根目录中查找 tsconfig 文件，而不是在 src 目录中.

• Copied tslint.json, tsconfig.app.json, and tsconfig.spec.json from a newly generated CLI 8 project to my project root.
• Deleted tslint.json, tsconfig.app.json, and tsconfig.spec.json from the src directory.
• Edited tsConfig values in angular.json to look for tsconfig files in project root, instead of in src directory.

如果您对 CLI 生成的 tsconfig 文件进行了任何修改，将它们从 src 移动到根目录并编辑其中的路径可能会更容易.我没有更改生成的文件，所以我只是从一个新项目中复制.

If you made any modifications to the tsconfig files generated by the CLI, it might be easier to move them from src to the root, and edit the paths in them. I didn't change the generated files, so I just copied from a new project.

我不知道生成 Web Worker 和添加 tsconfig.worker.json 是什么意思，这会在升级的 Angular 项目中引发问题.从 7 升级工作正常，直到我添加了一个工人.

I have no idea what it is about generating a Web Worker and the addition of the tsconfig.worker.json that throws a wrench in an upgraded Angular project. Upgrading from 7 worked fine until I added a worker.
