external extractor about binwalk HOT 5 OPEN

The errors say you need to install sasquatch and 7zip. Have you tried that?

see the deps.sh script in this repo

from binwalk.

We apologize for not being able to provide this information:

1. The tools needed in the alarm are installed normally by me as well as they are under the path of my system environment variables,
2. When he reported an error, I tried to cp these tools to the same directory as the tools installed in the deps.sh file of Binwalk, which is also the path of my environment variables, but it didn't work

from binwalk.

Ok, well, let's look closely at the error

WARNING: Extractor.execute failed to run external extractor 'mkdir 'squashfs-root' && mount -t squashfs '%e' 'squashfs-root'': 'module' object has no attribute 'DEVNULL', 'mkdir 'squashfs-root' && mount -t squashfs '%e' 'squashfs-root'' might not be installed correctly

If I recall correctly, DEVNULL is an import from subprocess, intended to be used with functions like popen, so you can instruct it to use /dev/null for the stdin, stdout or stderr descriptors

It sounds like the import is failing. Are you on a system that does not have a /dev/null device?

I can't imagine any Python version removing this but I also haven't looked at 3.12, 3.11 subprocess docs

EDIT: See Python3 docs on subprocess. You can see DEVNULL still exists, and has existed in Python3 since 3.3. I do not know if it's present on Windows

You realize that several of these tools have special patches applied, yes? When you say "installed normally", do you mean by following the steps in dep.sh, or do you mean using an OS package manager?

Either way, it seems like a waste of time trying to troubleshoot something that wasn't installed "properly". Sure, it's not rocket science cloning, patching and building a few packages- but you're bound to do something slightly differently than the script does, and then run into cases that no other users have

Use the script and see if that helps

Finally, you should probably switch to https://github.com/OSPG/binwalk as this repository seems to now be officially moribund
