　勉強用にサクっと実行できる環境があれば嬉しかったのだが……。

手順

$ cargo install evcxr_repl

　失敗した……。以下ログ。

　ビルドエラー。要点を抜き出すと以下。

   Compiling rand_os v0.1.3
error[E0425]: cannot find value `PTRACE_GETFPXREGS` in module `libc`
error[E0425]: cannot find value `PTRACE_SETFPXREGS` in module `libc`

  build failed
  • libcってなに？
  • nixってパッケージマネージャ？

　どうすれば解決できるかわからん。諦めた。
