Trouble getting MUNET running

[aaronzhang194]

Hi,

I ran into some issue as a new user of MUNET. I was following the instructions in https://munet.readthedocs.io/en/latest/.

It defaulted "to user installation because normal site-packages is not writeable", and I added '/home/aaron/.local/bin' to my PATH as instructed.

When running "sudo munet", I got the following error:

---

aaron@OptiPlex-7060:~$ sudo munet
Traceback (most recent call last):
File "/home/aaron/.local/bin/munet", line 5, in
from munet.main import main
ModuleNotFoundError: No module named 'munet'

I am using Ubuntu 22.04.5 LTS:

---

aaron@OptiPlex-7060:~/munet$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 22.04.5 LTS
Release: 22.04
Codename: jammy

Out of curiosity, I tried reinstalling with sudo and then "sudo munet" works. However, the installation did give me the following warning:

---

WARNING: Running pip as the 'root' user can result in broken permissions and con
flicting behaviour with the system package manager. It is recommended to use a v
irtual environment instead: https://pip.pypa.io/warnings/venv

What could be the problem with the "pip install munet" w/o "sudo"? Should I be concerned with the warning with the "sudo pip install munet"?

Thanks.
Aaron

Hey Aaron,

The ModuleNotFoundError you are experiencing is likely because you ran sudo munet without inheriting the local environment variables. As per the note about sudo configuration (linked here in the docs), many users need to run sudo with the -E flag.

e.g: sudo -E munet

On a separate note, I am not aware of any issues that you should be concerned about when installing munet as root. The warning shown is unrelated to munet, and instead related to the standard pip recommendation of how to install python packages (i.e. install without sudo).

Thank you for pointing out the -E switch.
Indeed, the document talks about that. However, the example simply says "sudo munet" without the -E switch and I was blindly following that.
Can we fix that in the doc? It makes a beginner's life a lot easier.
