[BUG] Can't Install with Cargo

[Tahinli]

Hi, I saw this project couple minutes ago in Orhun's FrOSCon 2024 presentation and wanted to install immediately. Unfortunately I got error when I try cargo install atac
This is not happening with cargo install atac --locked

error: could not compile `boa_engine` (lib) due to 1 previous error
warning: build failed, waiting for other jobs to finish...
error: failed to compile `atac v0.18.0`, intermediate artifacts can be found at `/tmp/cargo-installGfCW6s`.
To reuse those artifacts with a future compilation, set the environment variable `CARGO_TARGET_DIR` to that path.

The --locked option also throws warnings about crates being yanked. So either way using cargo install has some issues.

Yep it throws warnings but at least compile and run. Since we can't follow every update of every dependency, locked will provide us consistency.

i just ran into this 'boa_engine' compilation fail today when trying to 'cargo install atac'.

installed rustc version is 1.79.0, as requested in the README.

edit: 'rustup update'd to rustc 1.81.0, 'boa_engine' still won't compile.

edit2: cloned the ATAC repo and both 'cargo run' and 'cargo build --release' result in a successful compilation.
this looks like some kind of crates.io packaging problem?

it seems the boa project tracked the issue here boa-dev/boa#3982, but somehow marked it as completed without ever referencing any commits that might have solved it.
