1.安装Go 至C:Program FilesGo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
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:goindlv-dap.exe dap --listen=127.0.0.1:65147 from e:gosrc DAP server listening at: 127.0.0.1:65147 Build Error: go build -o e:gosrc\__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:goindlv-dap.exe dap --listen=127.0.0.1:54129 from e:gosrc DAP server listening at: 127.0.0.1:54129 Build Error: go build -o e:gosrc\__debug_bin.exe -gcflags all=-N -l . # example.com/greetings .datatype.go:17:6: main redeclared in this block e:gosrcconstant.go:8:6: previous declaration .flowControl.go:5:5: bool_0 redeclared in this block e:gosrcdatatype.go:5:5: previous declaration .flowControl.go:6:5: name redeclared in this block e:gosrcdatatype.go:6:5: previous declaration .flowControl.go:9:6: main redeclared in this block e:gosrcdatatype.go:17:6: previous declaration .function.go:19:6: main redeclared in this block e:gosrcflowControl.go:9:6: previous declaration .structure.go:37:6: main redeclared in this block e:gosrcfunction.go:19:6: previous declaration . est1.go:5:6: main redeclared in this block e:gosrcstructure.go:37:6: previous declaration .variable.go:5:5: name redeclared in this block e:gosrcflowControl.go:6:5: previous declaration .variable.go:6:5: age redeclared in this block e:gosrcdatatype.go:7:5: previous declaration .variable.go:10:6: main redeclared in this block e:gosrc est1.go:5:6: previous declaration .variable.go:10:6: too many errors (exit status 2)
问题:无法使用vscode调试go程序?
Failed to run "go env" to find GOPATH as the "go" binary cannot be found in either GOROOT() or PATH(C:Windowssystem32;C:Windows;C:WindowsSystem32Wbem;C:WindowsSystem32WindowsPowerShellv1.0)
原因分析:vscode配置未设置系统变量;
解决方法:vscode配置设置系统变量即可;
问题:vscode的终端无法使用go命令?
G:gosrcmain>go version
'go' 不是内部或外部命令,也不是可运行的程序或批处理文件。
原因分析:账号未设置特权等级。
解决方法:以管理员启动vscode。
