[Vuejs]-Vue does not see the component from my plugin

This is wrong component name mistake. DevelopmentBuildAnywherePageVue is the VuePlugin, the file name from the second listing, but the component name is MyComponent. The mistake is in real project file name DevelopmentBuildAnywherePageVue was in the template instead of the component name MyComponent.

Thanks to @nada for paying my attention.
