Default error message (You must create pages/*.vue) is misleading
Since 6ec3661ce852308917a0e96f2dcbbb1e77fc12fe, `fsRoutes` is disabled by default. I personally don't see what's wrong with its being enabled, but it's not what is this issue about. The problem is, the default error message: *"You must create pages/\*.vue or export "router" in entry file!"* is now misleading, as simply creating `pages/index.vue` will not change anything.

Either `fsRoutes` should be re-enabled by default, or the message should be rephrased.
