Good Day
I’m having trouble executing the square pattern vis rosrun command. When I run it, nothing happens, prompt is gone and nothing happens with BB8.
From other posts here that relate to this exercise, I check and have the required files. When I run the script with python it works.
Well I did follow lesson 3 and experimented with the permissions but as you can see in the screen I did have the proper "x"s
Take a look at my errors, looks like I’m getting stuck at the beginning with problem in the dependency “geometry…”
*** to update, that folder /var/mail is empty when I checked
Hello @ralves
Again thank you for coming to the rescue. The line you suggested is in my .py file. I just copied the whole thing in lesson 2. You can see it in the first screenshot. I checked the directory and found that /env is a exe file and python it self is sitting in the /usr/bin, so I tried that “#! /usr/bin python” but with similar effect so I just went back to the original that included /env
I see that @tesfayewakessa also had the same problem. Maybe he can share what he did.
I just deleted the contend of the move_bb8_square.py and copied again from lesson 2. Works like a charm now. Guess some problem during the original copy/paste
I used the IDE to do the delete and paste this time and not the “vi” editor.
Originally I used the "CTRL-C’ and “CTRL-V” into the vi, maybe some undesired character got created.
