error: failed to select a version for the requirement `unicode-width = "^0.1.4"`
candidate versions found which didn't match: 0.2.0
location searched: directory source `/usr/share/cargo/registry` (which is replacing registry `crates-io`)
required by package `clap v2.34.0`
    ... which satisfies dependency `clap = "^2.33"` of package `zram-generator v1.1.2 (/home/pterjan/rpmbuild/BUILD/rust-zram-generator-1.1.2-build/zram-generator-1.1.2)`
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.
