I'm creating this error in order to help other developer who could have the same problem. I spent some time on it and the solution is pretty easy.
The scenario was: everything was working fine locally and I double checked if the configuration in cloubuild was the same. (In my case, it happened on cloudbuild, but it could happen on any server)
But there, I got the following error:
./src/app/shared/markdown-editor/markdown-editor.constant.ts:56:0-35 - Error: Module not found: Error: Can't resolve 'easyMDE' in '/workspace/frontend/src/app/shared/markdown-editor'
./src/app/shared/markdown-editor/markdown-editor.directive.ts:620:0-35 - Error: Module not found: Error: Can't resolve 'easyMDE' in '/workspace/frontend/src/app/shared/markdown-editor'
Error: src/app/shared/markdown-editor/markdown-editor.constant.ts:1:26 - error TS2307: Cannot find module 'easyMDE' or its corresponding type declarations.
1 import * as EasyMDE from 'easyMDE';

Error: src/app/shared/markdown-editor/markdown-editor.directive.ts:2:26 - error TS2307: Cannot find module 'easyMDE' or its corresponding type declarations.
2 import * as EasyMDE from 'easyMDE';
The point is: Local everything was working but I was in a macOS and it is not case sensitive, but cloudbuild is linux based.
In order to solve it, check if the library you are using has capital letters and use only lower-case letters:
import * as EasyMDE from 'easymde';
instead of:
import * as EasyMDE from 'easyMDE';
