rustup target add wasm32-unknown-unknown

@Artoria2e5 你的rust版本太新了,我这用不了太新的特性.建议makefile保留原来的编译选项,并且新建一个新的选项用于使用新特性

makefile中第23行后面要加一个then.
sh中if后面要跟;then的.(shell中的一个大坑,都有分号了,还要写then)

[Artoria2e5]

是我大意了，我其实没有在用 Makefile（因为 git bash 没有 make）。我切进 Cygwin 里面试吧。

那个 -Z 确实不能 stable。我暂时没有什么修的意向，因为那样需要改两份 Cargo.toml。
