I am trying to use scapy and netfilterqueue with python 3.6.1. I created an environment with these installed.. as netfilterqueue will not work on python 3.9.

When I try to run my script: pipenv run python3 test.py

it runs in the correct environment but I get:

PermissionError: [Errno 1] Operation not permitted

When I try to run with sudo: sudo pipenv run python3 test.py

I get:

Warning: Python 3.6.1 was not found on your system…
You can specify specific versions of Python with:
  $ pipenv --python path/to/python

I've verified my libraries are correctly installed on the environment but am just not sure how to pass permissions to run a script. Thanks!

  • How did you set up the project before running `pipenv run python3 test.py`? – chepner May 13 '21 at 15:02
  • I used `pipenv install ` , which I believe makes the environment too if it doesn't already exist.. and that seemed to work. Then I changed the versions of python manually in the two pipefile's in the environment folder. – Tim May 13 '21 at 15:47

  • thanks but my issue is it won't let me run the script with sudo. – Tim May 13 '21 at 17:14

I did have similar issue. I managed to solved by running the virtual environment's Python executable with sudo. For example if your virtualenv is ./AwesomeProject, then you could run sudo ./AwesomeProject/bin/python to use the script with the virtualenv with root privileges.

To find where your the virtual environment's Python executable (Ex: ./AwesomeProject/bin/python), inside the virtual env run

whereis python
