Encountering a MatFormFieldModule error during npm start due to it not being recognized as an NgModule

Upon initially running npm start, I encounter the following error:

ERROR in MatFormFieldModule is not an NgModule. webpack: Failed to compile.

However, after making a file edit and saving, it compiles successfully without any issues. The cause of the initial error remains unclear.

I am utilizing @angular/material@^2.0.0-beta.12

Answer №1

After some trial and error, I finally figured out the fix for this problem. The issue was caused by mistakenly including MatFormFieldModule and MatInputModule in the @NgModule. Once I removed them, everything started working correctly. Big thanks to @Bohdan Khodakivskyi for pointing me in the right direction!
