Version of Delve is too old for Go version 1.20.0 (maximum supported version 1.19)

Question

When start debbugging session in GoLand I get this error:

WARNING: undefined behavior - version of Delve is too old for Go version 1.20.0 (maximum supported version 1.19)

I reinstall it with JetBrains Toolbox and didn't work. I uninstall it and install it manualy and didn't work!

The IDE maintainers say that GoLand didn't update delve when updating the IDE version in SOME CONDITIONS!

Answer 1

I found this workaround from the official issue.

1. Install dlv binary with go install github.com/go-delve/delve/cmd/dlv@latest
2. Set the dlv.path=<path_to_dlv_executable> under Help > Edit Custom Properties
3. Restart GoLand

It works for me.

Answer 2

Firstly install the latest version of delve based on the instructions here, https://github.com/go-delve/delve/tree/master/Documentation/installation

# Install the latest release:
$ go install github.com/go-delve/delve/cmd/dlv@latest

After installing the latest version of dlv, identify the path of the dlv executable file,

which dlv
# Output: /Users/<username>/go/bin/dlv

In your debug console check for the path that is used for running dlv /Users/<username>/Library/Application Support/JetBrains/IntelliJIdea2022.1/plugins/go/lib/dlv/macarm/dlv

Goto to the above path and follow the below steps,

mv dlv dlv.old # If the dlv is present 
ln -s /Users/<username>/go/bin/dlv dlv

Now you can rerun the application and you should be able to get the debugger working.
