Question

Python 2.7 Scapy 2.4

我尝试运行scapy的pdfdump（）演示，但得到OSError如下：

/>>> a=rdpcap("/home/zhangqiang/test.pcap") />>> a <test.pcap: TCP:1053 UDP:4 ICMP:0 Other:0>

/>>> a[423].pdfdump(layer_shift=1)

我收到了如下错误

ERROR: pdfdump(): executing 'acroread' failed Traceback (most recent call last): File "/home/zhangqiang/.local/lib/python2.7/site-packages/scapy/packet.py", line 526, in pdfdump subprocess.Popen([conf.prog.pdfreader, fname]) File "/usr/lib/python2.7/subprocess.py", line 390, in __init__ errread, errwrite) File "/usr/lib/python2.7/subprocess.py", line 1024, in _execute_child raise child_exception OSError: [Errno 2] No such file or directory

我搜索了这个问题，据说需要模块shlex。所以我导入了模块，但是引发了另一个错误。好像TeX不起作用。

/>>> import shlex

/>>> a[423].pdfdump(layer_shift=1)

The expression passed to TeX was:

  \PyXInput{86}%
After parsing the return message from TeX, the following was left:
  \*! Interruption.
  <*>

  ? Type <return> to proceed, S to scroll future error messages,
  R to run without stopping, Q to run quietly,

我如何解决这个问题？

Answer 1

您必须将conf.prog.pdfreader设置为要用于打开PDF文件的程序。例如：conf.prog.pdfreader = "evince"。

获取OSError：[Errno 2]在调用PyX的pdfdump（）时没有这样的文件或目录
