操作系统：MAC OS 10.14.x
zksync：https://github.com/matter-labs/zksync，master 分支
commit 899ca93052420c33583755cd2162143f461f36b3
需要注意的是，阅读完整源代码需要查看dev分支，master分支是提供编译后的各种执行程序。在以下安装时，请科学上网。
环境准备 zksync/docs/setup-dev.md
1、安装docker
brew cask install docker
2、安装Node & Yarn
brew install nodejs yarn
3、Axel
brew install axel
axel版本有差异，请采用axel 2.17.X，ubuntu、centos7、8环境，axel2.4、2.5版本均有问题，主要体现在执行：cargo install diesel_cli --no-default-features --features postgres无法通过。
4、Rust
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
rustc --version
rustc 1.46.0 (04488afe3 2020-08-24)
5、postgresql
brew install postgresql
6、Diesel cli
cargo install diesel_cli --no-default-features --features postgres
过程比较慢，耐心等待。。。
7、sqlx cli
cargo install sqlx-cli
8、solc
必须是v0.5.X
brew install solidity@5
9、下载zksync
git clone https://github.com/matter-labs/zksync.git
10、编辑~/. bash_profile:
export ZKSYNC_HOME=/path/to/zksync
export PATH=$ZKSYNC_HOME/bin:$PATH
到这里，环境依赖已经完成了
启动zksync zksync/docs/launch.md
1、设置本地运行环境
cd zksync/bin && ./zk #installs and builds zk itself
zk init #时间会比较久，耐心等待需要下载约8G的电路设置文件
初始化只需要一次即可，查看infrastructure/zk/src/init.ts
export async function init() {
if (!process.env.CI) {
await checkEnv();
await env.gitHooks();
await up();
}
await utils.allowFail(run.yarn());
await run.plonkSetup();
await run.verifyKeys.unpack();
await db.setup();
await contract.buildDev();
await run.deployERC20('dev');
await contract.build();
await server.genesis();
await contract.redeploy();
}
2、启动容器
zk up
查看infrastructure/zk/src/up.ts,该命令启动了geth 1，postgres，dev-ticker，tesseracts
export async function up() {
await utils.spawn('docker-compose up -d postgres geth dev-ticker');
await utils.spawn('docker-compose up -d tesseracts');
}
退出容器
zk down
3、运行zksync server
$ zk server
Finished release [optimized] target(s) in 1.28s
Running `target/release/zksync_server`
[2020-12-07T06:23:10Z INFO zksync_server] Running the zkSync server

第一次运行会编译rust，时间比较久，请耐心等待
查看infrastructure/zk/src/server.ts，用ts来编译、运行了core/bin/server/src/main.rs。
export async function server() {
await utils.spawn('cargo run --bin zksync_server --release');
}
关于etc/env/dev.env
这个文件是在init的时候从dev.env.example复制生成的。可以修改其中的参数，
如端口参数、出块间隔、见证者数量等。在本地的部署测试中，发现zk server的时候端口被占用的错误，首先请排查端口占用情况：lsof -i:8545,如果没有占用情况，那可以修改dev.env的端口在尝试一下。有需要的话，需要同步修改etc/js/env-config.js的端口。
4、运行zksync cli
cd bin && vim zcli #拷贝zk文件内容，作出相应修改
zcli文件内容：
#!/bin/bash
if [ -z "$1" ]; then
cd $ZKSYNC_HOME
yarn && yarn zcli build
else
# can't start this with yarn since it has quirks with `--` as an argument
node -- $ZKSYNC_HOME/infrastructure/zcli/build/index.js "$@"
fi
$ ./zcli #build xcli
$ zcli -h #查看命令行帮助
Usage: zcli [options] [command]
Options:
-V, --version output the version number
-n, --network <network> select network (default: "localhost")
