package install on Ubuntu 20.04 not working

auturgy commented 4 years ago

Fresh install on Ubuntu 20.04 not working Steps to reproduce: sudo apt install morse-simulator morse create my_first_sim morse run my_first_sim

Full console dump (of a different run, but same error) is at shorturl.at/svJM6 but basically Blender quits due to uncaught exception, AttributeError: 'Object' object has no attribute 'hide'.

09:23 $ morse --version morse 1.4

09:23 $ morse check

Checking up your environment...
Running on Linux. Alright.
Found MORSE libraries in '/usr/lib/python3/dist-packages/morse/blender'. Alright.
Trying to figure out a prefix from the script location...
Default scene found. The prefix seems ok. Using it.
Setting $MORSE_ROOT environment variable to default prefix [/usr/]
Checking version of /usr/bin/blender... Found v.2.82.7
Version 2.82.7 of Blender is untested but should work
Found Blender in your PATH (/usr/bin/blender, v.2.82.7). Alright, using it.
Checking version of Python within Blender /usr/bin/blender... Found v.3.8.2
Blender and Morse are using Python 3.8.2. Alright.
Your environment is correctly setup to run MORSE.

My first impression is that Blender API used in Morse is not compatible with your Blender version (2.82.7), MORSE is complaining about a missed attribute "hide". But, I have not checked in detail.

I use version 2.78c. So, could yo use an older Blender version? You could try with several ones, from 2.78c to 2.82.7, if you are interested in having latest Blender version.

The Blender game engine has been removed from Blender 2.8x, and MORSE can not run without it. The last version of Blender that should work is 2.79.

dgerod commented 4 years ago

@severin-lemaignan, this important information about Blender/BGE version should be written in the README to avoid people to have this problem.

severin-lemaignan commented 4 years ago

Indeed. Can you send a quick PR with this information?

Hi,

I met the same problem, but I change the version of the blender to 2.79b and then this exception was disappeared.

However, I meet another problem, when I run the first demo

morse run my_first_sim

It came out Segmentation fault

Did you meet before and how did you solve it?

Thank you.

severin-lemaignan commented 2 years ago

Can you post the content of /tmp/morse_default_autorun.crash.txt?

xinkai-jiang commented 2 years ago

Sorry, I change another machine using ubuntu 18.04 and fix all the problems, I guess it might related to ubuntu version. But in the previous environment, I cannot recover the exception before, and it came out with another fault.

But I guess it didn't write to /tmp/morse_default_autorun.crash.txt so I copy this file below for your reference.
