substrate开发配置

1. 配置rust环境

• 将stable版本设置为默认并更新rust

rustup default stable
rustup update

使用rustup show命令查看如下：

Default host: x86_64-apple-darwin
rustup home:  /Users/0x/.rustup

stable-x86_64-apple-darwin (default)
rustc 1.58.1 (db9d1b20b 2022-01-20)

• 添加nightly toolchains并更新

rustup update nightly

• 为nightly添加rust-src组件，添加WebAssembly(wasm)到target

rustup component add rust-src --toolchain nightly
rustup target add wasm32-unknown-unknown --toolchain nightly

使用rustup show命令查看如下:

Default host: x86_64-apple-darwin
rustup home:  /Users/0x/.rustup

installed toolchains
--------------------

stable-x86_64-apple-darwin (default)
nightly-x86_64-apple-darwin

active toolchain
----------------

stable-x86_64-apple-darwin (default)
rustc 1.58.1 (db9d1b20b 2022-01-20)

2. 配置crates.io代理

• 参考链接

https://rsproxy.cn/

• 修改~/.cargo/config文件,添加如下内容:

[source.crates-io]
replace-with = 'rsproxy'

[source.rsproxy]
registry = "https://rsproxy.cn/crates.io-index"

[registries.rsproxy]
index = "https://rsproxy.cn/crates.io-index"

[net]
git-fetch-with-cli = true

3. 安装ink相关

• 安装wasm压缩工具binaryen

brew install binaryen

• 安装cargo-contract插件

cargo install cargo-contract --vers ^0.16 --force --locked
