1.安装Go 至C:\Program Files\Go下；安装VScode至任意位置；创建go项目所在文件夹，E:\go，并在该文件夹下创建bin、pkg、src文件夹；bin用于存储二进制可执行文件，pkg存储包文件，src存储项目源码文件；
2.配置环境变量GOPATH（go项目所在的文件夹）、GOROOT(go语言安装所在的文件夹)；配置系统变量Path（）
3、启动vscode并安装go插件；
4、配置vscode中go的项目目录及go语言目录；
5、设置网络代理；如果你用的是linux或mac，直接在terminal中运行go env -w GO111MODULE=on和go env -w GOPROXY=https://goproxy.cn,direct，如果你是windows，就是在环境变量里设置GO111MODULE=on和GOPROXY=https://goproxy.cn,direct
6、安装项目环境必要的包及依赖包；（使用vscode时可省略）
go get -u -v github.com/nsf/gocode go get -u -v github.com/rogpeppe/godef go get -u -v github.com/golang/lint/golint go get -u -v github.com/lukehoban/go-find-references go get -u -v github.com/lukehoban/go-outline go get -u -v sourcegraph.com/sqs/goreturns go get -u -v golang.org/x/tools/cmd/gorename go get -u -v github.com/tpng/gopkgs go get -u -v github.com/newhook/go-symbols go get -u -v github.com/zmb3/gogetdoc go get -u -v github.com/cweill/gotests go get -u -v github.com/derekparker/delve/cmd/dlv go get -u -v golang.org/x/tools/cmd/guru go get -u -v github.com/fatih/gomodifytags go get -u -v github.com/haya14busa/goplay/cmd/goplay go get -u -v github.com/josharian/impl go get -u -v github.com/davidrjenni/reftools/cmd/fillstruct go get -u -v golang.org/x/tools/cmd/godoc go get -u -v golang.org/x/tools/cmd/goimports
包下载问题：golint下载失败？
C:\Users\chalon>go get -u -v github.com/golang/lint/golint
go get: github.com/golang/lint@v0.0.0-20210508222113-6edffad5e616: parsing go.mod:
module declares its path as: golang.org/x/lint
but was required as: github.com/golang/lint
解决方法：
7、vscode创建项目，编辑项目源文件，进行调试前安装必要的go调试插件；
安装创建后出现问题，提示如下内容：
Starting: E:\go\bin\dlv-dap.exe dap --listen=127.0.0.1:65147 from e:\go\src DAP server listening at: 127.0.0.1:65147 Build Error: go build -o e:\go\src\__debug_bin.exe -gcflags all=-N -l . go: go.mod file not found in current directory or any parent directory; see ‘go help modules‘ (exit status 1)
解决方法：
go module是go官方自带的go依赖管理库，可将某个项目下的所有依赖整理成一个 go.mod 文件,该文件里面写入了依赖的版本等；使用 go module 管理依赖后会在项目根目录下生成两个文件 go.mod 和 go.sum；之后我们可不用将代码放置在src下。
windows环境下，cmd进入项目文件夹执行： go mod init example.com/greetings
再次调试程序，出现错误：main（）重复定义，一个project只能有1个main()；
Starting: E:\go\bin\dlv-dap.exe dap --listen=127.0.0.1:54129 from e:\go\src DAP server listening at: 127.0.0.1:54129 Build Error: go build -o e:\go\src\__debug_bin.exe -gcflags all=-N -l . # example.com/greetings .\datatype.go:17:6: main redeclared in this block e:\go\src\constant.go:8:6: previous declaration .\flowControl.go:5:5: bool_0 redeclared in this block e:\go\src\datatype.go:5:5: previous declaration .\flowControl.go:6:5: name redeclared in this block e:\go\src\datatype.go:6:5: previous declaration .\flowControl.go:9:6: main redeclared in this block e:\go\src\datatype.go:17:6: previous declaration .\function.go:19:6: main redeclared in this block e:\go\src\flowControl.go:9:6: previous declaration .\structure.go:37:6: main redeclared in this block e:\go\src\function.go:19:6: previous declaration .\test1.go:5:6: main redeclared in this block e:\go\src\structure.go:37:6: previous declaration .\variable.go:5:5: name redeclared in this block e:\go\src\flowControl.go:6:5: previous declaration .\variable.go:6:5: age redeclared in this block e:\go\src\datatype.go:7:5: previous declaration .\variable.go:10:6: main redeclared in this block e:\go\src\test1.go:5:6: previous declaration .\variable.go:10:6: too many errors (exit status 2)
