构建失败，第一个底物链

问题描述

想根据他们的指南 [1] 逐步创建我的第一个底物链：https://substrate.dev/docs/en/tutorials/create-your-first-substrate-chain/

运行这个命令：cargo build --release 但得到这个错误：

    Compiling sc-chain-spec v3.0.0
    The following warnings were emitted during compilation:

warning: Assembler messages:
warning: Error: can't open /tmp/cc02CgnB.s for reading: No such file or directory

解决方法

WASM_BUILD_TOOLCHAIN=nightly-x86_64-unknown-linux-gnu cargo build --release 应该不需要包含 WASM nightly 工具链，这可能是基板 v2.0 所需要的，但基板 v3.0 不再需要

请按照guide here构建[节点模板v3.0：

git clone -b v3.0.0 --depth 1 https://github.com/substrate-developer-hub/substrate-node-template

cd substrate-node-template

# NOTE: you should always use the `--release` flag
cargo build --release
# ^^ this will take a while to do a release build!

在基于 arch 的 linux 中，您需要这些先决条件：

导出 OPENSSL_LIB_DIR="/usr/lib/openssl-1.0"

导出 OPENSSL_INCLUDE_DIR="/usr/include/openssl-1.0"

对于其他 ose，请查看 ./docs/rust-setup.md
