Compatible with Angular Ivy - Angular 9

[onilleksh]

ERROR in node_modules/ng-masonry-grid/ng-masonry-grid.module.d.ts:5:22 - error NG6002: Appears in the NgModule.imports of AppModule, but could not be resolved to an NgModule class.

This likely means that the library (ng-masonry-grid) which declares NgMasonryGridModule has not been processed correctly by ngcc, or is not compatible with Angular Ivy. Check if a newer version of the library is available, and update if so. Also consider checking with the library's authors to see if the library is expected to be compatible with Ivy.

I have updated my application to Angular 9. And this is what I am getting while building the application.

Angular CLI: 9.1.1 Node: 12.16.2 OS: linux x64

I was able to fix the same error for primeng by just updating its version to latest. Looking for a reply soon...

A work around for this issue (not perfect). Just disable the ivy in tsconfig.json.

...
"angularCompilerOptions": {
    ...
    "enableIvy": false
    ...
  }
...
