pcap-ng - 无法从 pcapng 导入 Filescanner

Question

尝试导入文件扫描器时出现以下错误，可能是什么原因造成的？

    from pcapng import scanner

Traceback (most recent call last):
  File "pcapng.py", line 1, in <module>
    from pcapng import scanner
  File "/Documents/script/pcapng.py", line 1, in <module>
    from pcapng import scanner
ImportError: cannot import name 'scanner' from 'pcapng' 

pip3 install python-pcapng
Requirement already satisfied: python-pcapng in /usr/local/lib/python3.7/site-packages (1.0)
Requirement already satisfied: six in /usr/local/lib/python3.7/site-packages (from python-pcapng) (1.14.0)

谢谢，
