I'm not able to reproduce this. Are you you using version 0.22.0 of the cli and the imported anchor-lang?

[S-Burns]

0.22.0 on Ubuntu WSL on Windows 10 loaded via the AWM & the same errors thrown with 0.20.1 installed with NPM before the upgrade. Following instructions on both verbatim.

[S-Burns]

Possible to upload the finalized versions of the modified lib.rs files etc.; maybe at the end of the book example...I think there are other requests for this.

[paul-schaaf]

have you uninstalled the npm version?

Ill upload the files tmr when Im back at my laptop

[S-Burns]

Yes. The NPM version was successfully removed. Anchor was off the machine, then reinstalled with the AWM and restarted with latest.

[paul-schaaf]

in the Cargo.toml of the program itself does it say anchor-lang = 0.22.0?

[S-Burns]

No. Now updated from 0.20.1 but this error is thrown...

[paul-schaaf]

this is a bug in the cli. Just change ProgramResult to Result<()> or copy the code from the book.

[S-Burns]

Success. Much thanks! Here is the complete, updated lib.rs for reference.

great! Im uploading the program to the repo currently
