我正在嘗試使用內(nèi)置的 Golang 調(diào)試 delve 將我自己的調(diào)試版本 Golang 應(yīng)用程序容器化。這是我如何在本地調(diào)試我的 Golang 應(yīng)用程序，它是一個非常簡單的 RSS 閱讀器。它從我感興趣的 RSS 提要中檢索數(shù)據(jù)。$on my local terminal$ dlv debug parsedata-xml-fp.go  # launch my app with delveType 'help' for list of commands.(dlv) b mainCommand failed: Location "main" ambiguous: main.main, runtime.main…(dlv) b main.mainBreakpoint 1 set at 0x760252 for main.main() ./parsedata-xml-fp.go:50(dlv) c> main.main() ./parsedata-xml-fp.go:50 (hits goroutine(1):1 total:1) (PC: 0x760252)=>  50: func main() {    51:         // [decode from response.Body]    52:         url := "https://foreignpolicy.com/feed/"    53:    54:         var URLset Rss    55:         if xmlBytes, err := getXML(url); err != nil {(dlv) l> main.main() ./parsedata-xml-fp.go:50 (hits goroutine(1):1 total:1) (PC: 0x760252)=>  50: func main() {    51:         // [decode from response.Body]    52:         url := "https://foreignpolicy.com/feed/"    53:    54:         var URLset Rss    55:         if xmlBytes, err := getXML(url); err != nil {(dlv) 在我的本地機器上，我可以設(shè)置斷點并進入我感興趣的函數(shù)。我試圖在我建造的容器內(nèi)做同樣的事情。選項 #1： 下面是我的容器的 Dockerfile#Dockerfile.dlvFROM golang:1.17 AS buildWORKDIR /COPY go/app/parsedata-xml-fp.go .COPY go.mod .COPY go.sum .    RUN go install github.com/go-delve/delve/cmd/dlv@latestRUN go build -gcflags="all=-N -l" -o /feedmeRUN echo $(ls /go/bin)# stage 2 build FROM ubuntu:18.04WORKDIR /EXPOSE 2345 COPY --from=build /go/bin/dlv /dlvCOPY --from=build /feedme /feedmeCOPY --from=build /parsedata-xml-fp.go /parsedata-xml-fp.goCMD ["/dlv", "--listen=:2345", "--headless=true", "--api-version=2", "--accept-multiclient", "exec", "/feedme"]當啟動我的容器并登錄時，出現(xiàn)錯誤：exec: "go": executable file not found in $PATH
