Prism 1.3 installation problem

#11 · 3. November 2020, 13:35

Hello!

I'm on 20.04 and have the same issue but haven't been as lucky with using python3 as Lukas. Maybe you can tell me if you did anything differently. I installed the apt package 'python-is-python3' and ran the 'Prism_setup_Linux.sh' but get the following error seemingly related to both PySide and PySide2:

Traceback (most recent call last):
File "Scripts/PrismInstaller.py", line 83, in <module>

I had no issue running `from Pyside2 import QtCore` in python.

On a sidenote Richard, how do you make line numbered codeblock here?

If you installed PySide2 on your OS you can delete this PySide folder, which might cause conflicts with your version:

/home/bastian/Software/Prism_v1.3.0.5_Linux/Prism/PythonLibs/Python37/PySide/

To get the numbered codeblock you click on "Formats" on the left side above the reply text you are writing and from "Enlighter Codeblocks" you can choose python or any other language.

Alright, I got it installed. But by installing PySide2 with pip3.

Wierdly enough Prism installation seems to start when not run with sudo. But then throws a permission error from what I guess is a Qt prompt. Yes that seems to be it. When I run "sudo python" and then "from PySide2 import QtCore" I get an import error:

ModuleNotFoundError: No module named 'PySide2'

Even though it imported fine when I ran python without sudo. It is a fairly fresh install of 20.04 and haven't done anything much besides installing Houdini, Blender and Unity. Now I ran "sudo pip3 install PySide2" and after prism installed without issue. Hope that helps if there's some changes to 20.04 you need to adjust for!

Can't see the "Formats" you refer to. Attached a screenshot of the comment editor, maybe it is different from yours?

Great that you got it working.

Looks like the format menu is only available for admin users. Unfortunately it looks like there is no setting in wordpress to change that.
