Getting the above error running Flightcrew on Sigil 1.3.0 on Ubuntu Linux 18.04.5 LTS.

Click Details returns:

Traceback (most recent call last):
  File "/usr/local/share/sigil/plugin_launchers/python/launcher.py", line 51, in <module>
    from opf_parser import Opf_Parser

ImportError: No module named parse

Any clues?

That's a puzzler. Urllib.parse is a python 3 standard library. Did you build Sigil 1.3 against the standard Ubuntu 18.04 system python 3?

[kevinhendricks]

Python 2 has urllib but no urllib.parse. Could you have built against python 2.7 somehow instead of python 3.5 or later?

[dougmassay]

You shouldn't be able to build Sigil against python 2 without a lot of finagling. But setting the path to the python2 binary in the plugin manager dialog might cause this.

[kevinhendricks]

Yes, that must be what is going on! Easy fix ... in the Plugin Manager 's Preferences Dialog, please make sure you have set a path to a Python 3.5 version and not a python 2.7 version.

[kevinhendricks]

Closing this as not an issue with flightcrew itself. User has not configured the plugin engine in Sigil properly.
