Installing pwntools from local repo

Question

I have the pwntools-dev repo cloned to my machine. Using the instructions on the pwntools installation page, I am trying to install from this local repo, but am failing.

The command I am typing and the terminal output are as below

david:~/Apps$ pip install --upgrade --editable ./pwntools

Apparently, I don't have the correct version of setuptools. But, when I check

david:~/Apps$ pip list | grep setuptools
setuptools              52.0.0

my setup tools does satisfy the requirement.

So, does anyone know what's going on and how I can fix this?

Edit: OK, so, on closer inspection, it appears that pwntools is looking for python 3.8 setuptools and, on not finding it because I have 3.9 on this machine, tries to download it and gets blocked by the corporate firewall. And no, I don't have access to 3.8 on this machine, so I've hit a brick wall and can go no further.

Are you sure you install everything apt-get install python3 python3-pip python3-dev git libssl-dev libffi-dev build-essential ? Are you using a venv ? Are you using an IDE shell ? Did you try outside the IDE ? I manage to install it on my computer. With either setuptools==52.0.0 or setuptools==68.0.0 on my Kunbutu 23.03 — RaiZy_Style

I'm sure your pip list is wrong.

david:~/Apps$ pip list | grep setuptools
setuptools              52.0.0

Because you can see that with those line :

      WARNING: Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'NewConnectionError('<pip._vendor.urllib3.connection.HTTPSConnection object at 0x7f559b51e220>: Failed to establish a new connection: [Errno -3] Temporary failure in name resolution')': /simple/setuptools/
      WARNING: Retrying (Retry(total=3, connect=None, read=None, redirect=None, status=None)) after connection broken by 'NewConnectionError('<pip._vendor.urllib3.connection.HTTPSConnection object at 0x7f559b51e550>: Failed to establish a new connection: [Errno -3] Temporary failure in name resolution')': /simple/setuptools/

pip is trying to get the setuptools from internet. And it failed, probably because you don't have internet.
I had the same log if I try to install pwntools without setuptools. And if you give pip -v you will be able to get the full command that has failed.

When I didn't have internet, nor setuptools installed it give me this :

~/Documents/1000.Autres/06.SO/01.Answer/install_pwntools » pip install --no-cache-dir --upgrade --editable ./pwntools -v

Where :

I don't have the reason to why pip list show setuptools but it's wrong

Thank you. Yes, that sounds as though it's the answer. I'll check tomorrow, when my head's back in the game.
@David, you should tick this answer as the correct one if it does what you want.
