Problem

When using cargo install cargo-expand the compilation fails due to a semver-breaking release of onig_sys. This does not happen when building the repo using cargo build. This is due to Cargo.lock being pinned to a non-breaking version of onig_sys. cargo install doesn't seem to take the lock-file into account when installing it directly from crates.io.

Solution

Workaround

As mentionned in the introduction, one can still install this directly from the repo because then the Cargo.lock file is honored. However one has to use cargo build --release and then copy the resulting binary into a folder in the $PATH.

Thanks! Looks like that did the trick, cargo install cargo-expand works again.

Hi, rust newbie here, not sure if this is related, but on Centos 7, cargo can't install v0.4.13 as it fails to compile onig_sys

cargo:warning=couldn't execute llvm-config --prefix (error: No such file or directory (os error 2))
cargo:warning=set the LLVM_CONFIG_PATH environment variable to a valid llvm-config executable

Like @barskern I managed to install expand 0.4.12 from source since its onig_sys is pinned on v69.1.0.

Install steps 

    git clone https://github.com/dtolnay/cargo-expand.git
    cd cargo-expand
    git checkout 0.4.12
    cargo check # onig_sys must be on v69.1.0
    cargo build
    cargo install --locked

However I could not for 0.4.13 as its pinned on v69.2.0, nor 0.4.12 from crates.io as I can't find a way to pin the version of onig_sys (might be related to rust-lang/cargo#2263).

See rust-onig/rust-onig#109

@LauH1987 could you try installing cargo-expand 0.4.14? I ended up pinning some deps to avoid that problematic version of onig_sys.

The real fix for this would be trishume/syntect#12. 🙏

Success. Thanks you for fixing this so quickly!
