You had better update cargo to the nightly version and then try it. If it keep in stuck error try comment commands, you may will need to study link.

From @apopiak

Are you on Apple M1? If, so there are currently issues with building rocksdb there. See here an approach: vikiival.medium.com/run-substrate-on-apple-m1-a2699743fae8

Also others have reported needing to:

You need clone the rust-rocksdb repo and checkout the commit listed here: https://github.com/substrate-developer-hub/substrate-node-template/issues/122 then you can create a config.toml file in your.cargo folder in your home directory and add a path to that cloned repo

Answer 5

You need to update the to this version: "6.20.3" checksum = "c309a9d2470844aceb9a4a098cf5286154d20596868b75a6b36357d2bb9ca25d"

am running on M1!
