go: GOPATH entry is relative; must be absolute path: "undefined".
For more details see: 'go help gopath'
exit status 2
Process exiting with code: 1

GOPATH is set in the environment correctly. This has worked for the past 2 months so something has changed today (Spet/5/2017) with an extension possibly.

We did update the way GOPATH was used in the debugger.

In your debug configuration in launch.json file, can you check if the program attribute is under your GOPATH/src ?

It is one level below src, $GOPATH/src/mymain. Where mymain contains the main go program. This is used to work before the extension update. Is there a way to install the previous version of this extension so this issue can be isolated to this extension update.

I also tried setting the GOPATH in the env map in launch.json but it results in the same thing.

This is the previous release: https://github.com/Microsoft/vscode-go/releases/tag/0.6.63
Scroll down until you see the link "Go-0.6.63.vsix"
Download that file and run code --install-extension Go-0.6.63.vsix from the location where you downloaded that file.

I can reproduce your error by having my package directly under the $GOPATH without the src folder. But you say that your package is under $GOPATH/src which puzzles me.

Nevertheless, I have the fix for case I was able to repro. Do you mind seeing if it fixes your issue as well?

You will need to download https://github.com/Microsoft/vscode-go/blob/master/Go-latest.vsix and then run code --install-extension Go-latest.vsix from the location where you downloaded that file.

@karamana I had issues with the new release so I uninstalled the extension and installed version 0.6.63 from a vsix file after disabling extension auto updating and everything is working again.

@karamana Is debugging the only feature broken for you or like @nais777 all the features are broken?

@karamana Are the other features of the extension like auto-complete, go to definition etc working as expected?

I have a fix in for GOPATH issue with the debugger. Can you try it out?

You will need to download https://github.com/Microsoft/vscode-go/blob/master/Go-latest.vsix and then run code --install-extension Go-latest.vsix from the location where you downloaded that file.

Thank you. This question has been bothering me for a long time. I have solved the problem after installing go-latest.vsix

That's good to hear @karamana
If you don't mind can you check a few things for me?

  • Set trace to "verbose" in your debug configuration
  • Start debugging, you will see verbose logging in the debug console
  • There will be a line Using GOPATH:

Is the value there a prefix for the value in the program attribute in the debug configuration?
Is the value there + /src a prefix for the value in the program attribute in the debug configuration?

Hi Ramya
VSCode 1.16.1. Arch: ia32
I updated to 0.6.65. Post update, I'm getting "go: GOPATH entry is relative; must be absolute path: "undefined"." error. launch.json has the following entry: "program": "${fileDirname}". Please advise.

@rajkrishnamurthy Can you share the debug configuration from the launch.json file?
Have you set GOPATH as an environment variable?
What is the Go version?

Hi Ramya
Sorry for the delay.
Once I set the GOLANG path, the problem went away., However, I never set the path variable prior to 0.6..65 upgrade.
Thanks very much.

Go version: 1.8.3
---launch.json---
{
"version": "0.2.0",
"configurations": [

    {
        "name": "Launch",
        "type": "go",
        "request": "launch",
        "mode": "debug",
        "remotePath": "",
        "port": 2345,
        "host": "127.0.0.1",
        "program": "${fileDirname}",
        "trace": "verbose",
        "env": {},
        "args": [],
        "showLog": true
    }
]

Am sorry, I dont do a lot of Go coding myself, so I wont be much of help here.
I would suggest you post your query in the Gophers Slack channel. I am sure there are others who have been in similar scenario.
