error: failed to select a version for the requirement `syn = "^1"`
candidate versions found which didn't match: 2.0.43
location searched: directory source `/usr/share/cargo/registry` (which is replacing registry `crates-io`)
required by package `diesel_derives v1.4.1`
    ... which satisfies dependency `diesel_derives = "~1.4.0"` of package `diesel v1.4.8 (/home/pterjan/rpmbuild/BUILD/diesel-1.4.8)`
perhaps a crate was updated and forgotten to be re-vendored?
As a reminder, you're using offline mode (--offline) which can sometimes cause surprising resolution failures, if this error is too confusing you may wish to retry without the offline flag.
