VS Code 1.60.1配置並調試golang

1.安裝Go 至C:\Program Files\Go下；安裝VScode至任意位置；創建go項目所在文件夾，E:\go，並在該文件夾下創建bin、pkg、src文件夾；bin用於存儲二進制可執行文件，pkg存儲包文件，src存儲項目源碼文件；

2.配置環境變量GOPATH（go項目所在的文件夾）、GOROOT(go語言安裝所在的文件夾)；配置系統變量Path（）

 3、啟動vscode並安裝go插件；

4、配置vscode中go的項目目錄及go語言目錄； 

 

5、設置網絡代理；如果你用的是linux或mac，直接在terminal中運行go env -w GO111MODULE=on和go env -w GOPROXY=https://goproxy.cn,direct，如果你是windows，就是在環境變量里設置GO111MODULE=on和GOPROXY=https://goproxy.cn,direct

6、安裝項目環境必要的包及依賴包；（使用vscode時可省略）

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創建項目，編輯項目源文件，進行調試前安裝必要的go調試插件；

安裝創建后出現問題，提示如下內容：

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)

 解決方法：

 go module是go官方自帶的go依賴管理庫，可將某個項目下的所有依賴整理成一個 go.mod 文件,該文件里面寫入了依賴的版本等；使用 go module 管理依賴后會在項目根目錄下生成兩個文件 go.mod 和 go.sum；之后我們可不用將代碼放置在src下。

windows環境下，cmd進入項目文件夾執行： go mod init example.com/greetings

 再次調試程序，出現錯誤：main（）重復定義，一個project只能有1個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 .

 問題：無法使用vscode調試go程序？

Failed to run "go env" to find GOPATH as the "go" binary cannot be found in either GOROOT() or PATH(C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0\)

原因分析：vscode配置未設置系統變量；

解決方法：vscode配置設置系統變量即可；

 

問題：vscode的終端無法使用go命令？

G:\go\src\main>go version
'go' 不是內部或外部命令，也不是可運行的程序或批處理文件。

原因分析：賬號未設置特權等級。

解決方法：以管理員啟動vscode。
