Getting a warning in every file in a nuxtJs

Question

I keep getting this doctor.md error for every {filename}.vue when open in my nuxtjs application

index.vue Doctor ❗ Incorrect Target Target version mismatch. You can specify the target version in vueCompilerOptions.target in tsconfig.json / jsconfig.json. (Expected "target": 2.7)

vue version: 2.7.15
tsconfig target: 3 (default)
vue: c:\Users\Tim\Documents\Nuxt\nuxt-app\node_modules\vue\package.json
tsconfig: Not found
vueCompilerOptions:
{
  "extensions": [
    ".vue"
  ]
}

What does it mean ? How to avoid this error ?
