Cannot compile

[h3x4d3c1m4l]

Hi! Unfortunately I can't get 0.10.0 and 0.10.1 to compile. The same error shows up on both Windows as well as macOS with the latest Rust version (1.71.1).

Thanks for reporting. Could you share the exact command you run to see this error?

The cause is definitely perhaps two different versions of crate toml are being used?, which points to either you needing to install with cargo install mdbook-admonish --locked or fixing your Cargo.toml if installing as a library.

Either way knowing your exact command would be useful for me to fix/clarify this for others 🙂

cargo install mdbook-admonish. Will try with --locked!

EDIT: works fine, thanks!!

Yep, so I think this is an unintentional breaking change in mdbook:

• Reverted the dependency update to the toml crate (again!). This was an unintentional breaking change in 0.4.32. Revert "bump 'toml' dependency" rust-lang/mdBook#2021

Looks to be being reverted, and the install can be mitigated with --locked, so closing as no further action required.

Should be mitigated fully now by #115 and released in 1.10.2
