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Web worker添加了更好的支持.我没有运气能使它工作.有人知道我在做什么错吗?
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?
使用此cli命令,我生成了网络工作者:
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.
此错误消息出现后:

推荐答案
我也遇到了这个问题,并注意到在一个新的Angular 8项目中,所有tsconfig.*.json
文件都位于根目录中,而只有根目录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.
这就是我所做的:
- 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
目录中删除tslint.json
,tsconfig.app.json
和tsconfig.spec.json
. - 在
angular.json
中编辑了tsConfig
值,以在项目根目录中而不是在src
目录中查找tsconfig文件.
- Copied
tslint.json
,tsconfig.app.json
, andtsconfig.spec.json
from a newly generated CLI 8 project to my project root. - Deleted
tslint.json
,tsconfig.app.json
, andtsconfig.spec.json
from thesrc
directory. - Edited
tsConfig
values inangular.json
to look for tsconfig files in project root, instead of insrc
directory.
如果您对CLI生成的tsconfig文件进行了任何修改,将它们从src
移至根目录并在其中编辑路径可能会更容易.我没有更改生成的文件,所以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,这在升级的Angular项目中会产生麻烦.从7升级可以正常工作,直到我添加一个工作程序为止.
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.
