python指令碼中pwntools gdb.attach遇到錯誤：Failed to read a valid object file image from memory.

******
Your encoding (ANSI_X3.4-1968) is different than UTF-8. pwndbg might not work properly.
You might try launching gdb with:
    LC_ALL=en_US.UTF-8 PYTHONIOENCODING=UTF-8 gdb
Make sure that en_US.UTF-8 is activated in /etc/locale.gen and you called locale-gen

一陣搜尋之後沒搞定。後來問了同學發現問題是python腳本里面忘加interactive了, 導致程式退出了。所以gdb attach不上。
