ImportError

[jamyspoon]

Hi,

I have troubles importing FreeCAD in a Python script.
Following the example in https://www.freecadweb.org/wiki/Embedding_FreeCAD, my script is:

Code: Select all

#!/usr/bin/env python
# coding: utf-8

import sys

sys.path.append('/snap/freecad/8/opt/local/FreeCAD-0.18/lib')

import FreeCAD

And the error message I got when executing:

Code: Select all

Traceback (most recent call last):
  File "/home/jamal/PycharmProjects/OptiSav/processes/freecad_stl.py", line 16, in <module>
    import FreeCAD
ImportError: libFreeCADApp.so: cannot open shared object file: No such file or directory

libFreeCADApp.so is in the same directory that I add to sys, just like FreeCAD.so
When I try to import libFreeCADApp.so first, the ImportError points to libFreeCADBase.so. And when I try to import libFreeCADBase, the ImportError points to libxerces-c-3.1.so, which is present in '/snap/freecad/8/usr/lib/x86_64-linux-gnu'. Appending this directory to sys.path does not help.

Ubuntu 18.04.3 LTS 64bit
Python '3.7.6 (default, Jan 8 2020, 19:59:22) \n[GCC 7.3.0]'
FreeCAD 0.18, Libs: 0.18R16093 (Git)

I've seen nothing but issues with the Snap version of FreeCAD.

You should probably install the stable package or the daily that is available in PPAs.

See the instructions in Install on Unix. Alternatively, use the AppImage.

Hi, I reinstalled FreeCAD using conda and now it works. Cheers !
