ERROR in ./node_modules/ngx-font-size/src/lib/ngx-font-size.module.ts
Module build failed (from ./node_modules/@ngtools/webpack/src/index.js):
Error: C:\source\Portal\node_modules\ngx-font-size\src\lib\ngx-font-size.module.ts is missing from the TypeScript compilation. Please make sure it is in your tsconfig via the 'files' or 'include' property.
The missing file seems to be part of a third party library. TS files in published libraries are often a sign of a badly packaged library. Please open an issue in the library repository to alert its author and ask them to package the library using the Angular Package Format (https://goo.gl/jB3GVv).
