我正在嘗試構建一個 Golang 項目，其中包含不同級別的包。我在這里上傳了一個示例項目：https ://github.com/David-Lor/archive.org-telegrambot/tree/example-go-dockerfile-not-building文件去.modmodule github.com/David-Lor/go-examplego 1.16require github.com/gammazero/workerpool v1.1.2DockerfileFROM golang:1.17.7WORKDIR /appCOPY ./src/go.mod .COPY ./src/go.sum .RUN go mod downloadCOPY ./src/* ./#RUN ls -lah # files are copied correctly; go.mod and main.go are in current directoryRUN go build -o /tmp/built錯誤當我 docker build 時，我在 go build 命令中收到以下錯誤：Step 7/7 : RUN go build -o /tmp/built ---> Running in 72358fb165c4main.go:8:2: no required module provides package github.com/David-Lor/go-example/internal/foo; to add it:        go get github.com/David-Lor/go-example/internal/foomain.go:9:2: no required module provides package github.com/David-Lor/go-example/internal/foo/bar; to add it:        go get github.com/David-Lor/go-example/internal/foo/barThe command '/bin/sh -c go build -o /tmp/built' returned a non-zero code: 1但是，如果我運行基本 docker 映像并從那里構建或運行應用程序，它可以正常工作（從主機系統也可以正常運行）：$ sudo docker run -it --rm -v $(pwd):/data golang:1.17.7root@e468a186536f:/go# cd /data/srcroot@e468a186536f:/data/src# go build -o /tmp/builtgo: downloading github.com/gammazero/workerpool v1.1.2go: downloading github.com/gammazero/deque v0.1.0root@e468a186536f:/data/src# /tmp/builtinternal/foointernal/foo/barroot@e468a186536f:/data/src# go run main.gointernal/foointernal/foo/bar
