`anchor test` fails for solana dev course example

[ouoabcde]

I'm encountering error when trying to run anchor test. Error is like below.

Unable to get latest blockhash. Test validator does not look started. Check ".anchor/test-ledger/test-ledger-log.txt" for errors. Consider increasing [test.startup_wait] in Anchor.toml. 

This is .anchor/test-ledger/test-ledger-log.txt file content.

Ledger location: .anchor/test-ledger
Log: .anchor/test-ledger/validator.log
Initializing...
Error: failed to start validator: Failed to create ledger at .anchor/test-ledger: io error: Error checking to unpack genesis archive: Archive error: extra entry found: "._genesis.bin" Regular

And here's .anchor/test-ledger/validator.log for the reference.

You might want to add extra startup time in Anchor.toml:

[test]
startup_wait = 10000

If that doesn't work, you can start the test validator with solana-test-validator, and run the tests with anchor test --skip-local-validator.

startup_wait setting didn't work, but anchor test --skip-local-validator works. Thank you :)

By default, MacOS includes BSD tar, but solana-test-validator requires GNU tar. To install GNU tar, use Homebrew:

brew install gnu-tar

Then, add the following line to your ~/.zshrc file:

export PATH="/opt/homebrew/opt/gnu-tar/libexec/gnubin:$PATH"

This will ensure that the GNU tar executable is in your system's PATH, allowing solana-test-validator to function correctly.

Hello @dividenconquer, I've tried your suggestion, but it's occurring same error.

export PATH="/opt/homebrew/opt/gnu-tar/libexec/gnubin:$PATH"

thanks this works well!
