* 符号链接法:

git clone https://github.com/golang/sys.git $GOPATH/src/github.com/golang/sys
git clone https://github.com/golang/net.git $GOPATH/src/github.com/golang/net
git clone https://github.com/golang/text.git $GOPATH/src/github.com/golang/text
git clone https://github.com/golang/lint.git $GOPATH/src/github.com/golang/lint
git clone https://github.com/golang/tools.git $GOPATH/src/github.com/golang/tools
git clone https://github.com/golang/crypto.git $GOPATH/src/github.com/golang/crypto

ln -s $GOPATH/src/github.com/golang/ $GOPATH/src/golang.org/x

* 手动创建目录法:

查看go env

E:\gocode\src\apiserver>go env
set GOARCH=amd64
set GOBIN=C:\go\bin
set GOCACHE=C:\Users\mingzhanghui\AppData\Local\go-build
set GOEXE=.exe
set GOFLAGS=
set GOHOSTARCH=amd64
set GOHOSTOS=windows
set GOOS=windows
set GOPATH=E:\gocode
set GOPROXY=
set GORACE=
set GOROOT=C:\go
set GOTMPDIR=
set GOTOOLDIR=C:\go\pkg\tool\windows_amd64
set GCCGO=gccgo
set CC=gcc
set CXX=g++
set CGO_ENABLED=1
set GOMOD=
set CGO_CFLAGS=-g -O2
set CGO_CPPFLAGS=
set CGO_CXXFLAGS=-g -O2
set CGO_FFLAGS=-g -O2
set CGO_LDFLAGS=-g -O2
set PKG_CONFIG=pkg-config
set GOGCCFLAGS=-m64 -mthreads -fmessage-length=0 -fdebug-prefix-map=C:\Users\MINGZH~1\AppData\Local\Temp\go-build802021134=/tmp/go-build -gno-record-gcc-switches

2. 创建目录E:\gocode\src\golang.org\x

mkdir -p %GOPATH%\src\golang.org\x

cd %GOPATH%\src\golang.org\x

3. 创建下载bat文件

** gitclone.bat

git clone https://github.com/golang/sys.git 
git clone https://github.com/golang/net.git 
git clone https://github.com/golang/text.git 
git clone https://github.com/golang/lint.git 
git clone https://github.com/golang/tools.git 
git clone https://github.com/golang/crypto.git

4. 切换到项目路径, go build
