go新环境Mac安装，包含okexchain

在一台全新的Mac电脑上搭建go环境：

1，下载go安装包

https://studygolang.com/dl # 中文网

https://golang.org/doc/install #官网

2，配置go path

$ go env

GO111MODULE=""
GOARCH="amd64"
GOBIN=""
GOCACHE="/Users/oker/Library/Caches/go-build"
GOENV="/Users/oker/Library/Application Support/go/env"
GOEXE=""
GOFLAGS=""
GOHOSTARCH="amd64"
GOHOSTOS="darwin"
GOINSECURE=""
GOMODCACHE="/Users/oker/go/pkg/mod"
GONOPROXY=""
GONOSUMDB=""
GOOS="darwin"
GOPATH="/Users/oker/go" # 编写代码存放的目录
GOPRIVATE=""
GOPROXY="https://proxy.golang.org,direct"
GOROOT="/usr/local/go"  # go安装的路径
GOSUMDB="sum.golang.org"
GOTMPDIR=""
GOTOOLDIR="/usr/local/go/pkg/tool/darwin_amd64"
GOVCS=""
GOVERSION="go1.16.3"
GCCGO="gccgo"
AR="ar"
CC="clang"
CXX="clang++"
CGO_ENABLED="1"
GOMOD="/dev/null"
CGO_CFLAGS="-g -O2"
CGO_CPPFLAGS=""
CGO_CXXFLAGS="-g -O2"
CGO_FFLAGS="-g -O2"
CGO_LDFLAGS="-g -O2"
PKG_CONFIG="pkg-config"
GOGCCFLAGS="-fPIC -arch x86_64 -m64 -pthread -fno-caret-diagnostics -Qunused-arguments -fmessage-length=0 -fdebug-prefix-map=/var/folders/h8/9n_7qfp153g3q8_jpb43hn2h0000gn/T/go-build397154971=/tmp/go-build -gno-record-gcc-switches -fno-common"

$ go version
go version go1.16.3 darwin/amd64

在 ~ 下

mkdir go

cd go

mkdir bin src pkg

vim ~/.zshrc

export GOPATH="/Users/oker/go"

此行的作用是告诉go，你的代码目录。

默认情况下我没有.zshrc文件，所以这里执行了：https://www.cnblogs.com/zccst/p/14633665.html

3，下载goland

4，编译okexchain

export GO111MODULE=on

export GOPROXY="https://goproxy.io"

make GenesisHeight=1121818 install

生成了okexchaind和okexchaincli，但不生效。

# 再次修改环境变量

vim ~/.zshrc

export GOPATH="/Users/oker/go"
export GOBIN="${GOPATH}/bin"
export PATH=$PATH:/usr/local/go/bin:$GOBIN
