Beta - Linux - svg.path can't find object 'Move'

[Rémi Devau]

Hello,

I’m using Ubuntu 18.04 and I’m not able to launch the Beta (fresh git pull) as is.
With a clean OS install, using setup_ubuntu and requirements.txt, I get this:

~/flatcam$ python3 FlatCAM.py
Traceback (most recent call last):
File "FlatCAM.py", line 6, in <module>
from FlatCAMApp import App
File "/home/cz/flatcam/FlatCAMApp.py", line 50, in <module>

from flatcamParsers.ParseSVG import *
File "/home/cz/flatcam/flatcamParsers/ParseSVG.py", line 24, in <module>
from svg.path.path import Move

But if I remove line 24 in flatcam/flatcamParsers/ParseSVG.py, everything is fine…
Did I miss something?

Hi Remi,

Make sure you use the latest version of the svg.path Python module. For Ubuntu:

pip3 install svg.path --upgrade

‌

Hi Marius,

I already did that:
cz@cz-X220:~/flatcam$ pip3 install --upgrade svg.path
Defaulting to user installation because normal site-packages is not writeable
Requirement already up-to-date: svg.path in /usr/local/lib/python3.6/dist-packages (4.0.2)

I tried uninstall/install, with or without sudo. No luck.

The Move class is available in the svg.path.path

Check inside the svg folder you have at least one file named “__init__.py”. If you don’t have it, create an empty one but using that name.

In Windows is like this:

The file is here.
I can see the class in path.py…

Anyway, I’ll try one more time with a new VM, (I have to admit I had some issue during python setup in last one)

Thank you for your support!

Also try to use Python 3.7.
I did made a try with Python 3.8 and there are at least some problems when issuing sys.exit(0) command. Who knows … there may be others in the different modules that are compiled for Python 3.8 …

It was confirmed by an user in the Discussions forum on FlatCAM.org that the problem was solved by replacing the svg.path.path file by the one in the svg.path GIT repository, meaning this one: https://github.com/regebro/svg.path/blob/master/src/svg/path/path.py

It seems that this is an issue of packing of the svg.path module in the used Linux repository. It is not a FlatCAM beta problem.

LE:
This is what user @lewbie has written on the mentioned forum:

In Ubuntu 18.04 ,

the path.py file of svg.path package which is installed by pip3 or apt-get did not contain class Move() section.
The path.py file obtained from github (regebro/…/path) contained the Move() section.

I copied the file into /usr/lib/python3/dist-packages/svg/path directory.

the problem solved

ha! it’s /usr/lib !
And not /usr/local/lib… My eyes didn’t want to see that /usr/lib/python3 was before everything else in my sys.path… and I never had a look in this folder.

It’s working now, thank you very much!
