Help with cargo-build-system error (Was: Re: Help with cargo-build-system error: chmod: No such file or directory)

Now I got this error instead:
https://github.com/swc-project/swc/issues/110
I get this error trying to build swc:
cargo build --release --all-features
error: failed to parse manifest at 
/tmp/guix-build-swc-0.0-1.2e22397f4.drv-7/source/ecmascript/ast/Cargo.toml

Caused by:
editions are unstable

Caused by:
feature edition is required

this Cargo does not support nightly features, but if you
switch to nightly channel you can add
cargo-features = ["edition"] to enable this feature

Does this mean our cargo does not support building swc?
