Kitties tutorial part 1 build is failing with unresolved import for sc_client_api RemoteBackend, anyone faced this issue? - rust

Question

I just followed the tutorial, I am at the first
cargo build --release
This is the error I am getting, any idea why this would happen?
error[E0432]: unresolved import `sc_client_api::RemoteBackend`
--> node/src/service.rs:4:39
|
4 | use sc_client_api::{ExecutorProvider, RemoteBackend};
| ^^^^^^^^^^^^^
| |
| no `RemoteBackend` in the root
| help: a similar name exists in the module: `StateBackend`

Answer 1

I solved this by removing RemoteBackend from the import at node/src/service.rs.
Just change the line (for me it was Line 4) at node/src/service.rs from
use sc_client_api::{ExecutorProvider, RemoteBackend};
to
use sc_client_api::ExecutorProvider;
While working with the tutorial cargo build --release resulted in the following error message:
error[E0432]: unresolved import `sc_client_api::RemoteBackend`
--> node/src/service.rs:4:39
|
4 | use sc_client_api::{ExecutorProvider, RemoteBackend};
| ^^^^^^^^^^^^^

| help: a similar name exists in the module: `StateBackend`
The help message provided some clue as to what was happening. Checking the node/src/service.rs file, I found that RemoteBackend was never referenced anywhere else in the file. So I simply removed it from the imports, and the build process was completed successfully.
