import package error

[jiufang171]

The following program sample.go triggers a panic: go version 1.15.3 on windows

package main

import (
	"github.com/traefik/yaegi/interp"
	"github.com/traefik/yaegi/stdlib"
	"github.com/traefik/yaegi/stdlib/syscall"
	"github.com/traefik/yaegi/stdlib/unrestricted"
	"github.com/traefik/yaegi/stdlib/unsafe"
)

func main() {
	goPath := "C:\\Users\\aihao\\go"
	i := interp.New(interp.Options{GoPath: goPath})
	i.Use(stdlib.Symbols)
	i.Use(syscall.Symbols)
	i.Use(unsafe.Symbols)
	i.Use(unrestricted.Symbols)

	_, err := i.Eval(`import "github.com/chromedp/chromedp"`)
	if err != nil {
		panic(err)
	}
}

Expected result:

$ go run ./sample.go
// output

Got:

$ yaegi ./sample.go
// output
