error: unwinding panics are not supported without std | = help: using nightly cargo, use -Zbuild-std with panic="abort" to avoid unwinding = note: since the core library is usually precompiled with panic="unwind", rebuilding your crate with panic="abort" may not be enough to fix the problem

这里panic_handler应该不算是lang_item吧，在死灵书中描述" #[panic_handler] 用于定义 panic! 在 #![no_std] 程序中的行为"，并没有lang="xxx"的标识（如之后的会报错提示的eh_personality和start lang_item），应该只算依赖吧（翻看原v3文档解释的比较清楚）
