Error 40 when exporting BOM

I did a search in the old threads but I didn’t find something similar.

From EESchema I’m trying the various BOM export scripts to find which one is better for my needs. Most of them fails with the following error, though:

Run command:
python "/usr/share/kicad/plugins/bom_html_with_advanced_grouping.py" "/home/andrea/myboard.xml" "/home/andrea/myboard"

Command error. Return code -1
Error messages:
execvp(python, /usr/share/kicad/plugins/bom_html_with_advanced_grouping.py, /home/andrea/myboard.xml, /home/andrea/myboard) failed with error 40!

I cannot understand what is “error 40”.
Here the list of the scripts that fail:

  • bom_html_with_advanced_grouping.py
  • bom_html_grouped_by_value.py
  • bom_sorted_by_ref.py
  • bom_csv_sorted_by_ref.py
  • bom_csv_grouped_by_value_with_fp
  • bom_csv_grouped_by_value.py
