Windows 10でpython3を使用していますpysharkを使用しようとしましたが、次のエラーが発生しました： 

Python 3.6.2rc1 (heads/3.6:268e1fb, Jun 17 2017, 19:01:44) [MSC v.1900 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import pyshark
>>> cap = pyshark.LiveCapture(output_file="pyshark.pcap")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Users\MYUSER\AppData\Local\Programs\Python\Python36\lib\site-
packages\pyshark\capture\live_capture.py", line 56, in __init__
self.interfaces = get_tshark_interfaces(tshark_path)
  File "C:\Users\MYUSER\AppData\Local\Programs\Python\Python36\lib\site-
packages\pyshark\tshark\tshark.py", line 140, in get_tshark_interfaces
tshark_interfaces = check_output(parameters, stderr=null).decode("ascii")
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 61: 
ordinal not in range(128)

または関数を作成するとき：

import pyshark

def cap():
    capture = pyshark.LiveCapture(interface='eth0')
    capture.sniff(timeout=50)
    print(capture)

cap()

そして、それを実行すると::
$_
次に、無限ループに入るか、そのままの状態で、ubuntu 16を使用してVMでテストします。

import pyshark
cap = pyshark.LiveCapture(interface='en0')
cap.sniff(packet_count=50)
for pkt in cap:
    print(cap)

そして、2 行目で VC を使用してデバッグすると、次のようになります。

Traceback (most recent call last):
  File "/home/MyVM/Desktop/program.py", line 1, in <module>
    import pyshark
ImportError: No module named pyshark

しかし、ターミナルで見ると：

$pip3 freeze

ターミナルを使用して実行すると、Windowsのように無限ループに入るか、ubuntuでpythonシェルを使用します

     raise RuntimeError("Program failed to run. Retcode: %d. Cmd: %s" % (retcode, cmd))
     RuntimeError: Program failed to run. Retcode: 2. Cmd: ['/usr/bin/tshark', '-D']
    >>>

そして、私はこのエラーが発生します

だから私はそれを修正するために私ができることを理解していません。
