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

我得到以下内容，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

}

Answer 1

请参见https://github.com/go-delve/delve/issues/1438。解决方法是将其放入 $ HOME / .dlv / config.yml：

替代路径： -{从：/，到：/ root}

Answer 2

在我的Ubuntu 18.04上，我看到文件的位置为〜/ .config / dlv / config.yml。这是一个示例：

substitute-path: - {from: /code, to: /home/foo/git/repo}

golang dlv无法看到source ::没有这样的文件或目录
