编译liquid合约出错 #20
Description
使用的rust配置：
[source.crates-io]
registry = "https://github.com/rust-lang/crates.io-index"
replace-with = 'ustc' # 如：tuna、sjtu、ustc，或者 rustcc
[source.ustc]
registry = "git://mirrors.ustc.edu.cn/crates.io-index"
[source.sjtu]
registry = "https://mirrors.sjtug.sjtu.edu.cn/git/crates.io-index"
[source.tuna]
registry = "https://mirrors.tuna.tsinghua.edu.cn/git/crates.io-index.git"
[source.rustcc]
registry = "https://code.aliyun.com/rustcc/crates.io-index.git"
1、执行 cargo test 时，出现以下错误：
error[E0635]: unknown feature proc_macro_span_shrink
--> /root/.cargo/registry/src/mirrors.tuna.tsinghua.edu.cn-df7c3c540f42cdbd/proc-macro2-1.0.47/src/lib.rs:92:30

92 | feature(proc_macro_span, proc_macro_span_shrink)
| ^^^^^^^^^^^^^^^^^^^^^^
error: aborting due to previous error
For more information about this error, try rustc --explain E0635.

To learn more, run the command again with --verbose.

error: build failed
2、使用清华大学的源
[source.tuna]
registry = "https://mirrors.tuna.tsinghua.edu.cn/git/crates.io-index.git"
执行cargo liquid build时，出现以下错误：

3、使用中国科学技术大学的源
[source.ustc]
registry = "git://mirrors.ustc.edu.cn/crates.io-index"
执行cargo liquid build时，出现以下错误：

个人建议，这个编译liquid合约的环境很难配置且容易出错，是否可以提供个docker组件，用户只需要将liquid合约上传到docker容器中，在容器里编译、构建，然后将构建好的Wasm 格式字节码及 ABI拷贝出来使用。
