mac os

1. 直接點擊go1.12.7.darwin-amd64.pkg ，進入圖形界面安裝。

2. 在~/.zshrc中，添加環境變量（如果是別的sh，請在別的sh中配置）

   #GOROOT
   export GOROOT=/usr/local/go/
   
   #GOPATH  go項目路徑
   export GOPATH=$HOME/workspace/project
   
   #GOPATH bin
   export PATH=$PATH:$GOPATH/bin
   
   #GOPATH root bin
   export PATH=$PATH:$GOROOT/bin

3. source ~/.zshrc

4. 驗證

   # go version
   go version go1.12.7 darwin/amd64
   # go env
   GOARCH="amd64"
   GOBIN=""
   GOCACHE="/Users/xumanshu/Library/Caches/go-build"
   GOEXE=""
   GOFLAGS=""
   GOHOSTARCH="amd64"
   GOHOSTOS="darwin"
   GOOS="darwin"
   GOPATH="/Users/xumanshu/workspace/project"
   GOPROXY="https://goproxy.io"
   GORACE=""
   GOROOT="/usr/local/go"

linux

1. 解壓 tar xzvf go1.12.7.linux-amd64.tar.gz -C /usr/lib/

2. 在~/.bashrc中，添加環境變量（如果是別的sh，請在別的sh中配置

   #GOROOT
   export GOROOT=/usr/lib/go
   
   #GOPATH go項目路徑
   export GOPATH=/root/gocode
   
   #GOPATH bin
   export PATH=$PATH:$GOPATH/bin
   
   #GOPATH root bin
   export PATH=$PATH:$GOROOT/bin

3. source ~/.bashrc

4. 驗證

   [root@compute84 bin]# go version
   go version go1.12.7 linux/amd64
   [root@compute84 bin]#
   [root@compute84 bin]# go env
   GOARCH="amd64"
