很明显这是没有找到库

Traceback (most recent call last):
  File "/home/giant/pwndbg/gdbinit.py", line 36, in <module>
    import pwndbg # isort:skip
  File "/home/giant/pwndbg/pwndbg/__init__.py", line 13, in <module>
    import pwndbg.arch
  File "/home/giant/pwndbg/pwndbg/arch.py", line 12, in <module>
    from capstone import *
  File "/home/giant/.local/lib/python3.6/site-packages/capstone/__init__.py", line 230, in <module>
    raise ImportError("ERROR: fail to load the dynamic library.")
ImportError: ERROR: fail to load the dynamic library.

我们可以去/home/giant/.local/lib/python3.6/site-packages/capstone/__init__.py 输出看看导入的库的路径(将下面的print输出注释掉，当然我这里已经将原来py2的输出改成py3了)

_lib_path = split(__file__)[0]
_all_libs = ['capstone.dll', 'libcapstone.so.3', 'libcapstone.so', 'libcapstone.dylib']
_found = False

for _lib in _all_libs:
    try:
        _lib_file = join(_lib_path, _lib)
        # print("Trying to load:", _lib_file)
        _cs = ctypes.cdll.LoadLibrary(_lib_file)
        _found = True
        break
    except OSError:
        pass

发现路径是/home/giant/.local/lib/python3.6/site-packages/capstone/

所以我们找一下find / -name libcapstone.so，再复制过去就可以了

cp /usr/local/lib/python2.7/dist-packages/capstone/lib/libcapstone.so /home/giant/.local/lib/python3.6/site-packages/capstone/
