Inkscape 1.2.1 - SBo seems to be missing one dependency(?)

MDKDIO · 07-17-2022, 11:57 AM

I went through all my installed SBo rel. packages, and noticed that I had missed updating Inkscape.

So once sorted all listed dependencies, I had it installed and running ok.

But, there's an error if one goes into menu Extensions -> Manage extensions
I get this for error(s):

import cssselect
ModuleNotFoundError: No module named 'cssselect'

I'm not sure if I've had this "problem" before as I rarely use the Extension Manager...

Anyway, I installed the cssselect SlackBuild and now I get the result expected (no error messages at all)

So, is it a missing dependency, or is there something newly added to Inkscape that cause the "problem"?

Yes cssselect requirement popped up at this end as well. The maintainer of the inkscape slackbuild is aware of this; also the numpy dependency should preferably be renamed to numpy3 (i.e. python3).

python-cssselect is indeed a (runtime-only) dependency of Inkscape since Inkscape 1.2

Another similar runtime-only dependency is CacheControl, which is needed by the Import Web Image feature.

Thanks both of you!!

numpy3 I already figured out being needed instead of numpy, should've reported that I guess...

CacheControl I did miss as I'm not using that function. But just checked here, and can confirm its being required as well.

If I run pip install CacheControl I don't get the error, but upon using the search I get a new error...

/usr/lib64/python3.9/site-packages/bs4/element.py:15: UserWarning: The soupsieve package is not installed. CSS selectors cannot be used

I do have python3-soupsieve-2.3.2-x86_64-2_SBo installed (might need a rebuild or something...)

I also notice this at the end of the error message:

NOTE: In order to use the FileCache you must have
lockfile installed. You can install it via pip:
pip install lockfile

SBo's SlackBuild for lockfile is bit old, latest version is 0.12.2 (not 0.8). So maybe that need some attention as well (am about to test a build of 0.12.2, reporting back once done)

Edit: Ponce is hosting the 0.8 version, so I'm guessing there's a reason for not using a newer version of lockfile...
But download link seems not to be working, nothing happens

Edit2:
I used the DL link in the .info file found on Ponce repo for current instead, worked fine.

Still no joy, I keep getting the error "missing soupsieve package", and lockfile is still reported as missing...

I gave it another go by removing lockfile and CacheControl

pip uninstall CacheControl (as user)
removepkg lockfile (as su)

Now if I install lockfile and CacheControl, using pip (as user)
pip install lockfile
pip install CacheControl (I of course ended up with CacheControl 0.12.11 when I did this).

Now Import Web Image is working, but after awhile I get the error again regarding soupsieve

Quote:

/usr/lib64/python3.9/site-packages/bs4/element.py:15: UserWarning: The soupsieve package is not installed. CSS selectors cannot be used.
warnings.warn(

And yes, the error message is incomplete...

Extensions Manager is now fully working (from what I can see) when trying it out...

Edit:
If I install soupsieve using
pip install soupsieve
it is fully working, but it'll install 2.3.2.post1

So I tried with re-building the python3-soupsieve using the 2.3.2.post1 version instead. No joy...
