    import binwalk
  File "/workspace/firmware-mod-kit/src/binwalk-2.1.1/src/binwalk/__init__.py", line 3, in <module>
    from binwalk.core.module import Modules, ModuleException
  File "/workspace/firmware-mod-kit/src/binwalk-2.1.1/src/binwalk/core/module.py", line 16, in <module>
    import binwalk.core.plugin
  File "/workspace/firmware-mod-kit/src/binwalk-2.1.1/src/binwalk/core/plugin.py", line 5, in <module>
    import imp
ModuleNotFoundError: No module named 'imp'

This because imp module has been removed.

Temp fix

Edit this file firmware-mod-kit/src/binwalk-2.1.1/src/binwalk/core/plugin.py

• Remove import imp
• Add this to top of file

import importlib.util
import importlib.machinery

def load_source(modname, filename):
    loader = importlib.machinery.SourceFileLoader(modname, filename)
    spec = importlib.util.spec_from_file_location(modname, filename, loader=loader)
    module = importlib.util.module_from_spec(spec)
    # The module is always executed and not cached in sys.modules.
    # Uncomment the following line to cache the module.
    # sys.modules[module.__name__] = module
    loader.exec_module(module)
    return module

• Replace imp.load_source with load_source
