I have updated Anchor to ^0.29.0, Solana to 1.16.18 (did try 1.17.4), and Rust Compiler to 1.73.0. The anchor build runs successfully, however, the anchor test always throws this exception. I have tried every possible set of versions in the last 2 days without any positive results.

thread 'main' panicked at 'called Option::unwrap() on a None value', cli/src/lib.rs:3128:55 note: run with RUST_BACKTRACE=1 environment variable to display a backtrace

Does anyone know how to fix it? thanks in advance.

  • Also I recognize a weird behaviour. After reset the laptop, if I run the yarn first, I will got the error mentioned above. However, if I run the anchor test first, it will pass the test but I will get the error of zsh: segmentation fault yarn when run any yarn commands.

  • I also tried with yarn 4.0 but the error still persists.

  • You should probably submit an issue to Anchor directly at github.com/coral-xyz/anchor/issues, this seems like a bug

It seems like a conflict between yarn and anchor. Remove all the yarn-related files and use pnpm instead, it will work perfectly.

I may keep this problem open because this solution is a workaround and not solve the root.
