Parsoid doesn't start

Question

I installed parsoid from its official repository, and configured it correctly by adding my Mediawiki API to /etc/mediawiki/parsoid/settings.js. I also removed the Interwiki options from my /usr/lib/parsoid/src/api/localsettings.jsfile, because they seem to be replaced by the parsoidConfig.setMwApi option in the settings.js file.

When running nodejs /usr/lib/parsoid/src/api/server.js from the command promt, I get the following error message:

[fatal][worker][4915] uncaught exception object is not a function
TypeError: object is not a function
    at new ParsoidService (/usr/lib/parsoid/src/api/ParsoidService.js:43:12)

    at startup (node.js:119:16)
    at node.js:902:3
[warning][master][4882] worker 4911 died (1), restarting.

When I run service parsoid start and service parsoid status I am always getting the information, that there is no parsoid process running.

Can someone explain me why Parsoid does not work?

Answer 1

It seems that your /etc/mediawiki/parsoid/settings.js and or /usr/lib/parsoid/src/api/localsettings.js is broken, and Parsoid is crashing as soon as it tries to look at your parsoidConfig. I recommend going through the instructions at https://www.mediawiki.org/wiki/Parsoid/Setup#Configuration carefully, and if you still have problems then please post excerpts of your settings files.
