I am assuming you are on the latest version of VS Code (1.26.0). If so, an upstream issue microsoft/vscode#56301 is being tracked for this in the VS Code repo.

This is most likely related to an issue with electron throwing SIGPIPE error when passing stdin to a badly spawned process.

Please run Go: Install/Update Tools and update all the Go tools. Follow this up with closing all instances of VS Code and restarting.

I'm having exactly the same issue with ms-vscode.go. Is there a quick fix I can make locally before the next updates?

[ramya-rao-a]

So the upstream electron issue occurs when we try to spawn a process using a command that is not found and then pipe stdin.
Previously this would have resulted in a ENOENT which we catch and show an appropriate msg.
I have pushed a fix to try and catch such a case earlier.

The only place we use spawn and stdin is during formatting and providing auto-completions. The former handled the case of missing command well and the latter didn't for which I pushed a fix.

With the below fix, you should see a prompt for installing gocode instead of the SIGPIPE error. Go through with the prompt and install the tool and you should get your completions back.

Please try the below and let me know if it fixes the issue

• Close all instances of VS Code
• Download https://github.com/Microsoft/vscode-go/blob/master/Go-latest.vsix
• Run code --install-extension Go-latest.vsix
• If the above fails with Error: end of central directory record signature not found, then clone this repo and use the Go-latest.vsix file from the cloned repo
• Reload VS Code

Thank you so much for the quick reply and for acting so fast on it!

I'm sorry but I don't believe it worked :(
I tried installing it both from the command line and from visual code "Install from VSIX".
This is the output I have from the terminal:

➜  service git:(staging) ✗ code --install-extension ~/Downloads/Go-latest.vsix
Extension 'Go-latest.vsix' was successfully installed!

Maybe I'm doing something wrong?

@juliofarah Can you run Go: Install/Update Tools and install all the tools and retry?

[mgitkin-vz]

Installing the latest version you linked above worked for me 🎉

Thanks @ramya-rao-a !

[juliofarah]

It worked!

Thanks @ramya-rao-a !

@ramya-rao-a This issue is still occurring sporadically when I save a file. Not sure if its related to gofmt

[ramya-rao-a]

@mgitkin-vz Can you try to run Go: Install/Update Tools to ensure you have all the tools in the right place and see if you still see the issue?

[calvn]

@ramya-rao-a Also encountering this issue. I've installed the workaround and ensured that all the tools are up-to-date. The extension host still crashes on save.

[mgitkin-vz]

@ramya-rao-a Yes, I ran Go: Install/Update Tools after installing the new extension version

@calvn @mgitkin-vz

• Can you consistently repro on file save?
• The upstream electron issue may effect other extensions as well. Can you disable other extensions you might have installed other than Go and try?
• Do the logs (Help -> Toggle Developer Tools -> Console) have any other helpful information?
