When I run the command : solana-test-validator
I got the following result.

Result

I don't know what the last line( note: run with RUST_BACKTRACE=1 environment variable to display a backtrace) mean.

Please help.

There are two questions here.

First, to run a command with an environment variable, you can simply define it before running your command, so in this case:

RUST_BACKTRACE=1 solana-test-validator

Second, regarding the specific Solana problem, this is an issue in the recent release, v1.7.9. Try rolling back to the previous Solana SDK, v1.7.8, by running:

solana-install init 1.7.8
