Comment 20 for bug 1664554

I have installed Inkscape 0.92.4 (5da689c313, 2019-01-14) on Windows10 and get the same mesage when trying to save a JessyInk pdf/png zip

Traceback (most recent call last):
  File "jessyInk_export.py", line 172, in <module>
    e = MyEffect()
  File "jessyInk_export.py", line 80, in __init__
    inkex.errormsg(_("Could not find Inkscape command.\n"))
NameError: global name '_' is not defined

I changed the JessyInk_export.py and now I get the message

"Das JessyInk-Skript ist in dieser SVG-Datei nicht installiert oder hat eine andere Version als die JessyInk-Erweiterung. Bitte wählen Sie "install/update..." aus dem "JessyInk" Untermenü des "Erweiterungen" Menü, um das JessyInk-Skript zu installieren oder zu aktualisieren." (Org)

"The JessyInk script is not installed in this SVG file or has a different version than the JessyInk extension. Please select "install/update..." from the "JessyInk" submenu of the "Extensions" menu to install or update the JessyInk script."

When I install/update nothing changes.

I installed Inkscape portable on an external drive and the same problem occurs.

Before I only used the portable version on a different external drive and it worked very wee.
