Failed to load manifest for dependency

I am getting this error:

error: failed to load manifest for workspace member `/Users/Xavier/rust/t3rn/node/standalone`

Caused by:
failed to load manifest for dependency `circuit-standalone-runtime`

Caused by:
failed to load manifest for dependency `pallet-circuit`

Caused by:
failed to load manifest for dependency `t3rn-protocol`

Caused by: 
failed to read `/Users/Xavier/rust/t3rn/protocol/Cargo.toml`

Caused by:
  No such file or directory (os error 2)

Try to verify by check. It seems that the create dependency package cannot be found by mistake. You can change the acceleration source suitable for your current region in your configuration file

If you need to replace the source, you can Add a config configuration file under the cargo directory and configure the source

cd ~/.cargo

vim config
[source.crates-io]
registry = "https://github.com/rust-lang/crates.io-index"

Thanks for responding; it didn't work.

The file /Users/Xavier/rust/t3rn/protocol/Cargo.toml doesn't exist, and it must exist. Make sure there's a crate at this path. If you don't expect it to be, find why t3rn-protocol is trying to use it, and possibly delete it from there.

Thank you, It turned out there wasn't a crate with that path.
