$ rustc --explain E0544
Feature attributes are only allowed on the nightly release channel. Stable or
beta compilers will not comply.
Erroneous code example:
#![feature(lang_items)] // error: `#![feature]` may not be used on the
// stable release channel
If you need the feature, make sure to use a nightly release of the compiler
(but be warned that the feature may be removed or altered in the future).
This seems to have solved it for me:
$ rustup install nightly
$ rustup run nightly cargo build
This project looks really cool! But the build fails with an error. The full transcript is below...
