I just created an Anchor project with anchor init and tried to run anchor test but it didn't work. I always get the error:

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.

If I try using solana-test-validator I get the error Error: failed to start validator: Failed to create ledger at test-ledger: blockstore error

I increased the startup_wait value in Anchor.toml file but it didn't work as well:

startup_wait = 100000

My log file shows the following:

The versions I'm using are:

anchor-cli 0.26.0
solana-test-validator 1.15.2
rustc 1.67.0

Any suggestion?

Try this combination:

rustc 1.65.0
solana-cli 1.14.12
anchor-cli 0.26.0

Solana 1.15 doesn't seem to currently work with Anchor 0.26. Was also getting errors when upgrading to Anchor 0.26 and found a working combo by referencing the versions used on Solpg.

  • Hi John, I tried, but unfortunately, it didn't work as well. Still stuck on this. :-(

  • This is correct. There was an issue with the 1.15.2 release, so be sure to re-install the earlier versions until 1.15.3 is released using solana-install init 1.14.12 and also using the 1.14.12 crates
