After running commend nmp run serve on my vue project I'm getting this two error. I am using class based vue like in this tutorial. This error occurred for all my vue imported files. I am a new in a vue, and I don't understand why this error happening, I have "vue-class-component": "^7.2.6", "vue-property-decorator": "^9.0.2", like in this tutorial and I are also importing this in my app.vue file. Author do not have this error on his video, I can find an article about this error on the internet
my main problem is this error
Module parse failed: Unexpected character '@' Vue Class-Bassed
and
11:0 error Parsing error: Using the export keyword between a decorator and a class is not allowed. Please use `export @dec class` instead.
