库的角度示意图：构建原理图会产生角度10的误差

如何解决库的角度示意图：构建原理图会产生角度10的误差

根据关于库https://angular.io/guide/schematics-for-libraries的原理图的Angular文档，我尝试运行脚本以npm run build https://angular.io/guide/schematics-for-libraries#building-your-schematics来构建原理图

"scripts": {
    "build": "../../node_modules/.bin/tsc -p tsconfig.schematics.json","copy:schemas": "cp --parents schematics/*/schema.json ../../dist/my-lib/","copy:files": "cp --parents -p schematics/*/files/** ../../dist/my-lib/","copy:collection": "cp schematics/collection.json ../../dist/my-lib/schematics/collection.json","postbuild": "npm run copy:schemas && npm run copy:files && npm run copy:collection"
  }

它记录以下错误

'..' is not recognized as an internal or external command,operable program or batch file.
npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! library-name build: `../../node_modules/.bin/tsc -p tsconfig.schematics.json`

npm ERR! This is probably not a problem with npm. There is likely additional logging output above.
npm WARN Local package.json exists,but node_modules missing,did you mean to install?

执行../../node_modules/.bin/tsc -p tsconfig.schematics.json时出现错误

P.S。我正在使用Angular-10创建库。谢谢。
