I try to start up my web app by 'ng serve', I get this error. Can't figure out why.
I am not really sure what the error is even telling me. I have tried to update all dependencies. I have looked at almost all the similar question solutions and they have not worked. I can't tell if it is a compiler error, typescript, or a dependency error.
