cargo liquid build 出错

[2473o]

如下所示:

root@119bcf939882:~/hello_world# cargo liquid build
[1/4] d(・ω・d) Collecting crate metadata

修改内容：

注释

https://github.com/rust-lang/rust/issues/109807 https://github.com/CosmWasm/cosmwasm/issues/1727 应该是1.70+的工具链生成的wasm二进制带了mvp以外的opcode

rust-lang/rust#109807 CosmWasm/cosmwasm#1727 应该是1.70+的工具链生成的wasm二进制带了mvp以外的opcode

可以尝试按装下面我修改后的cargo-liquid工具，然后再cargo liquid build试试

cargo install --git https://github.com/bxq2011hust/cargo-liquid --branch main --force

我的环境是 ubuntu 22.04 server LTS，这个仓库的Binaryen wasm-opt 不带--signext-lowering， 可以从binaryen下载 还有就是修改下template下的rust-toolchain.toml ，内容还是channel = "nightly-2023-01-03"🙂
