Inkscape Extensions Not Working
Workaround available Windows, macOS, Linux Updated November 13, 2026Based on 4 user reportsHow we research
Quick answer
Extensions fail when Python or required modules are missing, or when Inkscape was started from the command line on macOS. Check the error, install the dependencies, and update to the current release.
Most likely fix: Read the error
How to fix it
Try these in order — the most common fix is first.
1. Read the error
- Run the extension; the dialog shows a Python traceback naming the missing module
- Install it with your package manager (Linux, e.g. python3-appdirs, python3-lxml)
Did this fix it?2. macOS
- Launch Inkscape from Applications or Launchpad rather than the terminal
- Update to the newest build
Did this fix it?3. Install extensions correctly
- Edit > Preferences > System > User extensions to see the folder
- Unzip the extension folder there and restart Inkscape
- Use Extensions > Manage Extensions if your network allows it
Did this fix it?4. Reinstall
- Use the official installer instead of a distro or AppImage build if bundled Python is broken
Did this fix it?
Symptoms
Extensions greyed out, Manage Extensions spins forever or an error mentioning Python or a missing module appears.
Why it happens
- Missing Python modules (e.g. appdirs, lxml, requests) on Linux packages
- Inkscape started from a terminal on macOS: extensions blocked by a 1.4.3 security feature (1.4.4 draft lists it as a known issue)
- Manually installed extensions in the wrong folder
- Antivirus or permissions blocking the bundled Python
