[INFO] [stderr] error: Cannot set `RUSTC_BOOTSTRAP=1` from build script of `simd v0.2.4 (/opt/rustwide/workdir)`.
[INFO] [stderr] note: Crates cannot set `RUSTC_BOOTSTRAP` themselves, as doing so would subvert the stability guarantees of Rust for your project.
[INFO] [stderr] help: If you're sure you want to do this in your project, set the environment variable `RUSTC_BOOTSTRAP=simd` before running cargo instead.
