如何解决尝试运行我的 Angular Schematics 时出错
从我的项目的根文件夹运行 schematics .:schema
时,出现以下错误:
An error occured:
Error: Cannot find module '/Users/pete/Desktop/projects/Angular/DEV/SchematicsDemo/src/my-component/index'

我正在关注此 YouTube 视频 https://www.youtube.com/watch?v=M5YSPas3qFo&t=1707s 中的教程,他在 32:30 首次尝试时收到了同样的错误。
为了修复它,他运行了 npm run build:watch
,但我在尝试执行相同操作时收到此错误
npm ERR! missing script: build:watch
npm ERR! A complete log of this run can be found in:
npm ERR! /Users/pete/.npm/_logs/2020-12-26T17_18_10_036Z-debug.log
这是我的 angular.json

不知道如何解决这个问题,任何帮助将不胜感激!
解决方法
这个问题已经在github上登录过,你可以用#12230关注同一个问题。
但在此之前它已解决,您可以使用以下解决方法,您必须稍微调整 angular.json
改变
projects.YOUR-APP-NAME.targets
到
projects.YOUR-APP-NAME.architect
