Solving "ModuleNotFoundError: No module named 'gudev'"

[pitosalas]

If this is a duplicate, I apologize. I wrote this issue 10 minutes ago and it's not showing up. Either I forgot to press "submit" or for some reason you decided to delete it.

I am traveling the same road you seem to be traveling, about 1 week behind. I am using Linorobot, on noetic which requires python3. It is on ubuntu 20.04 - which is not exactly your configuration but I am hopeful that your solutions will work for me. I've also perused many of your issues to see if I could find a solution. I am well on the way but not there yet. The problems are with lino_install/install.sh (which I see you had to and recorded some changes.) I think further that the problems are because of python3.

The specific step that I am asking about is:

~/linorobot_ws$ rosrun lino_udev lino_udev.py which for me is giving this error:

[onboard:bullet]~/linorobot_ws$ rosrun lino_udev lino_udev.py
Traceback (most recent call last):
  File "/home/ubuntu/linorobot_ws/src/linorobot_src/lino_udev/scripts/lino_udev.py", line 3, in <module>
    import gudev
ModuleNotFoundError: No module named 'gudev'

I have tried a bunch of things that looked like they would solve it but they've not worked. I suspect I am somewhat dirtying up my environment with these experiments.

Do you have any tip or suggestion? Thanks!

Sorry for being slow coming coming back to you.

Not sure if this helps but compared to the steps in the install file I had to modify 3 other instructions that touched python:

python-gudev ***replaced with gir1.2-gudev-1.0

*** added sudo apt install python-is-python3

sudo easy_install pip ***replaced with sudo apt install python3-pip

Hi Michael

Thanks for the response! I ended up solving it myself by just erasing everything and starting over. So I am all set now. Thanks again.

Sorry for being slow coming coming back to you.

Not sure if this helps but compared to the steps in the install file I had to modify 3 other instructions that touched python:

python-gudev ***replaced with gir1.2-gudev-1.0

*** added sudo apt install python-is-python3

sudo easy_install pip ***replaced with sudo apt install python3-pip

If this is a duplicate, I apologize. I wrote this issue 10 minutes ago and it's not showing up. Either I forgot to press "submit" or for some reason you decided to delete it.

I am traveling the same road you seem to be traveling, about 1 week behind. I am using Linorobot, on noetic which requires python3. It is on ubuntu 20.04 - which is not exactly your configuration but I am hopeful that your solutions will work for me. I've also perused many of your issues to see if I could find a solution. I am well on the way but not there yet. The problems are with lino_install/install.sh (which I see you had to and recorded some changes.) I think further that the problems are because of python3.

The specific step that I am asking about is:

~/linorobot_ws$ rosrun lino_udev lino_udev.py which for me is giving this error:

[onboard:bullet]~/linorobot_ws$ rosrun lino_udev lino_udev.py Traceback (most recent call last): File "/home/ubuntu/linorobot_ws/src/linorobot_src/lino_udev/scripts/lino_udev.py", line 3, in import gudev ModuleNotFoundError: No module named 'gudev'

I have tried a bunch of things that looked like they would solve it but they've not worked. I suspect I am somewhat dirtying up my environment with these experiments.

Do you have any tip or suggestion? Thanks!
