Unable to start debugging on .go files due to path error

[festum]

Only happened on Golang files both portable version and install version. Debugging on another language(like Python) works well.
msg:

The program "${file}" does not exist: Error: ENOENT: no such file or directory, lstat 'C:\fe0\bin\VSCode\App\VSCode\${file}'

vs code version: 1.10.2
go version: 1.8

Any ideas?

Can you share your debug configurations from launch.json ?

Can you share the complete error and your launch.json?

Looks like the error is coming from https://github.com/Microsoft/vscode-go/blob/c530ed4c7cae1038df630307ff9a5eb173714e53/src/debugAdapter/goDebug.ts#L206

(VSCode) Try opening the folder where the .go file exists in. Don't open the .go file independently. Or VSCode could not create/read the .vscode folder nor the debug file.

bviktor has the same problem:

• VSCode Version: 1.11.2
• OS Version: 1703 15063.138

Steps to Reproduce:

1. Get a VM image for win10 15.15063 from modern.ie

2. start it up, install updates, restart

3. install vs code with defaults

4. install go runtime with defaults

5. start vs code

6. install go extension, restart vs code

7. create a new .go file:

package main
import "fmt"
func main() {
  fmt.Println("foobar")
}

8. ctrl+f5

Expected output: foobar printed

Actual output:

The program "${file}" does not exist: Error: ENOENT: no such file or directory, lstat 'C:\Program Files (x86)\Microsoft VS Code\${file}'

On the top the following appears:

Error: Failed to continue: "The program attribute must point to valid directory, .go file or executable."

Which you can either "close" or "open launch.json" but if you try the latter, nothing happens at all.

bviktor Can you share your debug configuration from the launch.json file?

[gaocuo]

Can not found any launch.json in the work dir and whole disk.

Hit the same error.
Does anyone can tell me where is the file launch.json?

[jiaoyk]

same issue. No launch.json could be found on disk.

[ramya-rao-a]

The launch.json file would be in the .vscode folder in your workspace.
It gets created when you click on the gear icon in the debug view
If it doesn't exist, then VS Code tries to use some default configuration and tries to debug the current file that is open in the active editor.

This default configuration uses the ${file} variable which should resolve to the current file that is open in the active editor.

It appears that ${file} doesn't resolve properly in your cases.

I cannot repro it though.

Can one of you share a sample simple repo where this happens?
And share details like

• which folder in this repo have you opened in VS Code?
• which file was open when you triggered debug?
• how did you trigger debug?

Ramya Rao (@ramya-rao-a) the opening post provides a step-by-step guide to reproduce the issue.

Actually, it's the opening post of microsoft/vscode#25138

Thanks bviktor

I can repro now.
The case is when there is no workspace open in VS Code but only a Go file is.
