ERROR in NgSemanticModule is not an NgModule

[varepato]

Whenever I try to run the server, I always get this error:
"ERROR in NgSemanticModule is not an NgModule"
I followed all the steps of installation, the only thing that fixes this is saving again the same app.modules.ts file. ¿Why is this happening?
