@marcelgoya What is the output of just running npx ng run app:build:production?

[marcelgoya]

Hi, problem solved. I had some errors inside my html templates and running the cmd above displayed them for me. Everything is now working as expected. Thanks!

[imhoffd]

@marcelgoya Mind if I keep this open? It's a bug if the Ionic CLI doesn't print the error from the Angular CLI. It's odd though, I can't seem to reproduce this issue.

Can I ask if the error you received was particularly lengthy (thousands of characters)?

[marcelgoya]

@dwieeb Sure, feel free. Strange, I didn't see any console output.

[imhoffd]

@marcelgoya Was the error you received particularly lengthy (thousands of characters)?

[marcelgoya]

No, it only said that it couldn't compile but it didn't output any specific details

Have the similar problem on macOS 10.14 when running ionic cordova run android --verbose --no-interactive command.
