I created a go project and tested the following code, got the same error

go 1.25.1

package main

import (
	"fmt"
	"os"
	"path/filepath"
	"sync"
)

func main() {
	println(executableDir())
}

var executableDir = sync.OnceValue(func() string {
	exe, err := os.Executable()
	if err != nil {
		panic(err)
	}
	// ↓↓↓↓
	exe = "C:/Users/admin/.vscode/extensions/typescriptteam.native-preview-0.20251213.1-win32-x64/lib/tsgo.exe"

	exe, err = filepath.EvalSymlinks(exe)
	if err != nil {
		panic(fmt.Sprintf("bundled: failed to evaluate symlinks: %v", err))
	}
	return filepath.Dir(exe)
})

↓ Also got the same error

var executableDir = sync.OnceValue(func() string {
	exe, err := os.Executable()
	if err != nil {
		panic(err)
	}
	// ↓↓↓↓
	println(exe)
	// output: C:\Users\admin\AppData\Local\Temp\go-build4127866348\b001\exe\main.exe

	exe, err = filepath.EvalSymlinks(exe)
	if err != nil {
		panic(fmt.Sprintf("bundled: failed to evaluate symlinks: %v", err))
	}
	return filepath.Dir(exe)
})

go build main.go
main.exe

got the same error

C:\Users\admin\Desktop\demo\main.exe
panic: bundled: failed to evaluate symlinks: The system cannot find the path specified. [recovered, repanicked]

Can you provide more info about your system? Are all of your files living within a symlink somehow?

[fooooooooooooooo]

i have the same error, vscode is installed with scoop to C:/Users/user/scoop/apps/vscode/1.107.0 and the data directory is symlinked to C:/Users/user/scoop/persist/vscode/data

package main

import ("path/filepath")

func main() {
  _, err := filepath.EvalSymlinks("C:/Users/user/scoop/apps/vscode/1.107.0/data/extensions")

  if err != nil {
    panic(err)
  }
}

errors with

panic: The system cannot find the path specified.

After each system installation, I link the D:\UserDir\admin to C:\Users\admin . ( this keeps my data )

mklink /J C:\Users\admin D:\UserDir\admin

I moved main.exe out of the admin directory and everything went fine.

The code ran successfully,

If you're able to build from source, can you try #2381? Theoretically you could just swap the binary into where your extension lives.

I downloaded the source code and compiled it,
This bug has been perfectly fixed.
I can use tsgo now.
