'failed to select a version' error when running 'cargo test-bpf'

Question

I am writing unit tests for a native rust program using solana-sdk, solana-program-test and assert_matches crates. After writing the tests, when I try to execute them using cargo test-bpf command, I am running into the below error:

Updating crates.io index
error: failed to select a version for the requirement "time = "^0.3"*
candidate versions found which didn't match: 0.3.15, 0.3.14, 0.3.13, ...

Answer 1

I have seen the cargo error failed to select a version for the requirement ... when I had mismatched dependency and/or rust versions.

Looking at the output, I see some 1.10.x and 1.14.x solana crate dependency versions; get all of these aligned on at least the same major if not the same minor release.
