delve - golang dlv 无法看到源::没有这样的文件或目录

Question

在 docker 容器中:

docker run \
                --rm -it \
                -p 80:80 \
                -p 2345:2345 \
                -v $(pwd)/src:/go/src/ \
                --security-opt="seccomp=unconfined" \
                --privileged \
                --cap-add SYS_PTRACE \
                golang bash

在 $GOPATH 的容器中:

go get -u github.com/derekparker/delve/cmd/dlv

dlv version
Delve Debugger
Version: 1.1.0
Build: $Id: 1990ba12450cab9425a2ae62e6ab988725023d5c 

dlv debug app --headless --listen=0.0.0.0:2345 --api-version=2

在 $GOPATH::的 mac 终端中

dlv version
Delve Debugger
Version: 1.1.0
Build: $Id: 1990ba12450cab9425a2ae62e6ab988725023d5c $

 dlv connect 127.0.0.1:2345

我得到以下信息，但无法列出来源？

dlv connect 127.0.0.1:2345
Type 'help' for list of commands.
(dlv) b main.go:29
Breakpoint 1 set at 0x7f584d for main.main.func1() /go/src/app/main.go:29
(dlv) c
> main.main.func1() /go/src/app/main.go:29 (hits goroutine(4):1 total:1) (PC: 0x7f584d)
(dlv) l
> main.main.func1() /go/src/app/main.go:29 (hits goroutine(4):1 total:1) (PC: 0x7f584d)
Command failed: open /go/src/app/main.go: no such file or directory

注意:我在 dlv 服务器和客户端中都在 $GOPATH 中:

在容器中:

ls $GOPATH/src/app
layout.html  main.go  mypack

在 mac 终端中:

ls $GOPATH/src/app
layout.html main.go     mypack

对比代码 launch.json:

        },
    ]
}

参见 https://github.com/go-delve/delve/issues/1438 .解决方案是将其放入$HOME/.dlv/config.yml:

替代路径: - {从:/，到:/root}
