+If you have problems with types using vue-meta, then you're most probably using vue-class-component.
+In any troublesome situation, just add the following ambient declaration to your types:
+
+```js
+import { MetaInfo } from 'vue-meta';
+
+declare module "vue/types/vue" {
+  interface Vue {
+    metaInfo?: MetaInfo | (() => MetaInfo)
+  }
+}
+```
