Unable to use delve: pacakge main is not in GOROOT

Question

This is my directory structure:

root
├── LICENSE
├── README.md
├── acceptor.go
├── cmd
│   ├── main
│   └── main.go
├── go.mod

I want to debug cmd/main.

I tried: dlv debug main.

I got an error:

package main is not in GOROOT (/usr/local/Cellar/go/1.15.5/libexec/src/main)
exit status 1

How to fix this?

Answer 1

When you call dlv debug main, you're telling delve to debug a package called main in the standard library, which obviously doesn't exist.

You must provide the full absolute, or relative path.

Absolute path:

dlv debug github.com/yourusername/root/cmd

Relative path:

dlv debug ./cmd
