Some extensions don't work with .48.2 and OSX 10.7.3

Known issue with Inkscape 0.48.2 on OS X Lion:
Bug #819209 “Extensions do not work with Mac OS X Lion”
<https://bugs.launchpad.net/inkscape/+bug/819209>

Unfortunately, we don't yet have packages of Inkscape 0.48.3.1 for Mac OS X available for downloading.

OK - many thanks.

I have seen mention of workarounds, and downloaded Windell Oakey's Eggbot extension 2.2.2.r2 but either it doesn't work for OSX10.7.3 or I have no idea how to correctly execute it (the latter is more likely in my opinion)

Does any of these guides help you? https://www.google.com/search?q=osx+install+lxml

@mafiaz - ever used a Mac?

@Darren - I did not and still would NOT recommend to you to try to install lxml yourself (there is no installer nor DMG for osx).

@Darren - to get python extensions working with the official Mac OS X package of Inkscape 0.48.2, a single line needs to be inserted into a "text file" (actually a shell script) inside the application bundle.

I can try to guide you to do this edit yourself if you want - one prerequisite though would be that you install a 'real' plain-text editor (Apple's TextEdit won't work because the new 'Autosave' feature on Lion can potentially modify such files in a way that would prevent the application from launching again).

"Free" text editors I could recommend:
- TextWrangler
  <http://barebones.com/products/textwrangler/>
- Sublime 2
  <http://www.sublimetext.com/2>
- Smultron (the old "free" and open-source version, not the one from the App Store):
  <http://sourceforge.net/projects/smultron/files/smultron/3.6b1/>

Another prerequisite would be that you install the original Inkscape app again (because we don't know what exactly happened (or not) when you tried to run the installer package from the Egg-Bot project).

@ mahfiaz - I got as far as looking for solutions to the apparent lxml issue but did not try to follow any - none appeared to include, or be specific for, OSX 10.7.3 anywa

@ suv - I would much appreciate an attempt to get them working yes. I also note that you do not recommend an attempt to install lxml myself

Steps to work around the known issue of python-based extensions not working with the official Inkscape 0.48.2 package on OS X 10.7 Lion:

Prerequisites:
- unmodified version of Inkscape 0.48.2 installed
- alternative text editor is available (see earlier comment)
- quit all open Inkscape windows

1) Open a new Finder window and browse to the directory where you installed Inkscape to (most likely '/Applications').
2) select 'Inkscape', open the context menu (with the right mouse button or 'Ctrl+mouse button' for single-button mouse or 'Ctrl+tap' with the trackpad) and choose the entry 'Show Package Contents'
3) within the package contents, browse to 'Contents > Resources > bin'
4) in 'Contents > Resources > bin' open the file 'inkscape' in a plain-text editor (use drag&drop for example, or 'Open with…' from the context menu)
5) once you have the file (a shell script) open in the text editor, go to line 32.
The content of line 32 is:

export VERSIONER_PYTHON_PREFER_32_BIT=yes

6) above line 32, insert a new line with this text:

export VERSIONER_PYTHON_VERSION=2.6

7) save the changes (make sure that no (hidden) file extension is added)
8) test Inkscape: launch the app and use for example 'Extensions > Render > Gear…' as test

If all went well, all python-based extensions (those from the menu 'Extensions' as well as those used for input/output extensions to support other file formats) will work now as expected.

If something went wrong, trash the modified application, install a fresh copy and report back here.

thankyou so much, this worked perfectly.

Many thanks

Darren

Hi suv,

I did modify the file and was able to get passed the lxml message. Now I get this error message:

Traceback (most recent call last):
  File "sozi.py", line 27, in <module>
    import pygtk
ImportError: No module named pygtk

I have installed pygtk through macports, and have also been successful in loading the module in python manually (i.e. executing python and then invoking "import pygtk). But still when I call sozi from inkscape I get the above noted error. I am using the latest table version for inkscape .48.2 and mac os x lion 10.7.3. Any suggestions would be highly appreciated.

If you already have MacPorts experience, why don't you install inkscape with macports as well? Then you'll have no conflicts between various python versions and python modules.

Getting the precompiled version of Inkscape working with sozi is a hack at best, see
<https://answers.launchpad.net/inkscape/+question/179289>
for an example.

@aorchard - sozi-related issues on OS X Lion would better be asked in a new question, or continued in <https://answers.launchpad.net/inkscape/+question/179289>:
- This one here (Q 194132) covers extensions shipping with Inkscape, and how to get them working for basic usage.
- Extensions like sozi or textext are externally developed custom extensions with a lot of additional dependencies which are not and cannot be fully covered by the official pre-compiled package of Inkscape for Mac OS X (it includes only the minimal requirements - libraries as well as python modules). Questions about sozi and other custom extensions which spawn external dialogs are beyond the scope of this question (Q 194132) IMHO.

@suv, thanks for the response, and I agree. WIll follow up on the other list you noted.

it works also for me, on mac os mountain lion, thank you ~suv (suv-lp)

I'm back I'm afraid, with the same "fantastic xlml wrapper..."error.

Inkscape .48.2 (freshly installed from inkscape.org - although not obviously .48.4 as indicated on download page)
OS 10.8.2
Python 2.7.3 (from python -V)

and line 32 and 33 of Inkscape in Contents/Resources/bin/inkscape read:

export VERSIONER_PYTHON_VERSION=2.6
export VERSIONER_PYTHON_PREFER_32_BIT=yes

any help appreciated, especially a process that might help identify the problem

I have tried to go to line 32 in the "inkscape" as you recommended, but I don't have the same text:

Can you help? I really would like to use the extensdions.

I am having the same issue. I have the latest XQuartz X1 Window manager 2.7.5 and the latest Inkscape installed - 0.48 - using the package from Inkscape. I am running OSX Mavericks 10.9.1 and Python based on Macports' version:
python --version
Python 2.7.6
I installed lxml via MacPorts and I should be able to use the filter to embed all images, but I get
The fantastic lxml wrapper for libxml2 is required by inkex.py and therefore this extension. Please download and install the latest version from http://cheeseshop.python.org/pypi/lxml/, or install it through your package manager by a command like: sudo apt-get install python-lxml

Any ideas?

Never mind. Adding export VERSIONER_PYTHON_VERSION=2.6 to the shell scripts as recommended here above, restarting X11 and Inkscape did work for my setup as well. :-)

This has fixed my issue with DXF, many thanks

Dave

This solved my problem, too.
Many Thanks.

Thanks suv!

That worked fine on my Mac running OS X 10.9.3 and Inkscape 0.48.2 r9819.

Hi, I am get the same problem with:
OSX 10.9.4
Inkscape 0.48.5 r10040
XQuartz 2.7.7 (xorg-server 1.15.2)
python --version: Python 2.7.8
The message, when I try to run sozi from Inkscape is:

"The fantastic lxml wrapper for libxml2 is required by inkex.py and therefore this extension. Please download and install the latest version from http://cheeseshop.python.org/pypi/lxml/, or install it through your package manager by a command like: sudo apt-get install python-lxml"

I suppose there is a PATH problem, but I cannot find where I have to add the needed one.

Could you help me? [many thanks, Ignacio]

Sozi is not supported out-of-the-box with Inkscape 0.48.5 on OS X - this
custom external extension requires PyGtk which is not included in the
application bundle because inkscape's own extensions use the internal
GUI and not PyGtk for dialogs.

I assume that you followed some random instructions found on the web,
likely based on some older package of Inkscape for OS X - without
details on what you already modified (inside the app bundle) and
installed outside of the app bundle, I'm sorry but there is no easy help
to provide (too many unknowns).

Your question is also off-topic for this thread (which is about a known
issue with an older package (Inkscape 0.48.2 for Mac OS X) - this known
issue was fixed in the current stable release package 0.48.5 for Mac OS X).

O.K., many thanks and sorry to introduce noise to the thread.

Sorry for not being more supportive. For starters, see

https://answers.launchpad.net/inkscape/+question/179289#comment-10

(the instructions had been written for 0.48.2, but probably work with
0.48.5 too: install the dependencies for sozi via Macports (at least
py27-lxml, py27-numpy, py27-pygtk), and create/modify the two files as
described).
