I tried compiling a statement that prints hello world and found that the generated executable file is too large. Is there a way to reduce the execution volume?

The size can be reduced by not including the full standard library symbols:

package main

import "github.com/traefik/yaegi/interp"

func main() {
  i := interp.New(interp.Options{})
  i.Eval(`println("Hello world")`)
}

The executable size is 6M instead of 24M if stdlib is included (i.Use(stdlib.Symbols)).

Can I choose to import only the required packages? If i.Use(stdlib.Symbols) is not used, some packages cannot be imported even if they are used

you have to write your own version of stdlib/stdlib.go , and include only the packages you need.
