Angular build error "export ‘ɵɵcomponentHostSyntheticListener’ (imported as ‘i0’) was not found in ‘@angular/core"

I am trying to stand up an Angular application that takes advantage of clarity UI. I am currently using Angular version 10.1.1. After installing/adding clarity, I get the following errors when trying to build.

ERROR in ./node_modules/@clr/angular/esm2015/utils/animations/expandable-animation/expandable-animation.js 33:8-43
"export 'ɵɵcomponentHostSyntheticListener' (imported as 'i0') was not found in '@angular/core'

ERROR in ./node_modules/@clr/angular/esm2015/utils/animations/expandable-animation/expandable-animation.js 35:8-39
"export 'ɵɵupdateSyntheticHostBinding' (imported as 'i0') was not found in '@angular/core'

ERROR in ./node_modules/@clr/angular/esm2015/utils/drag-and-drop/draggable-ghost.js 96:8-39
"export 'ɵɵupdateSyntheticHostBinding' (imported as 'i0') was not found in '@angular/core'

I done some playing around with versions thinking it could possibly be a bug in the newer versions, but to no avail. Here is my package.json

I am also deploying this to Heroku, but don’t think that is the problem here. I had it correctly working before adding clarity. Plus, I currently can’t deploy because my build is failing.
