As suggested in the previous post (many thanks to DiapDealer for the tip), this plugin requires
an external version of Python and some additional packages (PyQt5, qscintilla and pywin32) to work properly.
You can activate the required Python version in Sigil using the following procedure:
- from Sigil menu bar select: Plugins → Manage Plugins
- Uncheck ‘Use Bundled Python’ if checked
- Using the ‘Set’ button choose Python interpreter path (e.g.C:\Users\your_user\AppData\Local\Programs\Pyt hon\Python310)
You can read some more info in the attached userManual.epub (chapter 0-Quick start and chapter 4-Installing and starting).
Thank you for reading.
