Pyshark FileCapture不工作

Question

我是pyshark的新手，我通过搜索教程编写了一个示例代码

import pyshark
cap = pyshark.FileCapture("input.cap")
cap_1 = cap[0]

然后它会给我一个错误

/Users/tingyugu/anaconda3/bin/python /Users/tingyugu/PycharmProjects/final/test.py
Traceback (most recent call last):
File "/Users/tingyugu/anaconda3/lib/python3.6/site-packages/pyshark/capture/file_capture.py", line 70, in __getitem__
next(self)
File "/Users/tingyugu/anaconda3/lib/python3.6/site-packages/pyshark/capture/file_capture.py", line 60, in __next__
packet = self._packet_generator.send(None)
StopIteration

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
File "/Users/tingyugu/PycharmProjects/final/test.py", line 5, in <module>
cap_1 = cap[0]
File "/Users/tingyugu/anaconda3/lib/python3.6/site-packages/pyshark/capture/file_capture.py", line 73, in __getitem__
raise KeyError('Packet of index %d does not exist in capture' % packet_index)
KeyError: 'Packet of index 0 does not exist in capture'

我知道原因是盖子里没有包，但是我的朋友可以通过pyshark读取文件。

我使用的是python 3.6.0 anaconda，而pyshark是anaconda中的0.3.7

如果你使用的是jupyter，请参阅PyShark Repo上的this issue。我也有同样的问题，似乎pyshark和jupyter不太搭调。我假设ipython也会有同样的问题。在他们的repo上也有一些像this one这样的拉取请求作为修复，但还没有合并。
