[UPDATING] `dummy-registry` index
[ERROR] failed to select a version for the requirement `my-dependency = "^0.1.1"`
candidate versions found which didn't match: 0.1.2-pre.0
location searched: `dummy-registry` index (which is replacing registry `crates-io`)
required by package `package v0.0.0 ([ROOT]/foo)`
if you are looking for the prerelease package it needs to be specified explicitly
    my-dependency = { version = "0.1.2-pre.0" }
perhaps a crate was updated and forgotten to be re-vendored?
