I've been trying for days to track down a problem with my installation of MediaWiki 1.41.1, which I spent some time rescuing from a spam attack a while back. My NavBoxes aren't working, being replaced with "Lua error: Internal error: The interpreter exited with status 127." My understanding is that 127 is a "file not found" error, but I can't figure out what file it can't find. I'm not certain that it's related to NavBox specifically; I get the impression that it's a more general Lua issue, since I'm seeing the error in a nearly all my Templates and Modules.

Is there a way I can determine what file Lua is looking for? I've got $wgShowDebug set to true but I'm not seeing anything obvious in the logs... though I don't know for sure what exactly I'm looking for.

Okay, I can confirm that it's nothing to do with the Navbox: if I enter a simple command (like =p.Hello .. ', World!')into the Debug Console on any page, I get the status 127 error. My webserver does not allow executables outside of /usr/bin, so I have the following in my LocalSettings.php:

$wgScribuntoEngineConf['luastandalone']['luaPath'] = '/usr/bin/lua';

I'm sure this is something simple for someone familiar with Lua an Scribunto, but I'm at a loss...

Also, for each error it throws on the page (for example, a page where I have several NavBoxes), it includes this line in the log. Not sure if that's something normal or if it hints at anything:

[Scribunto] MediaWiki\Extension\Scribunto\Engines\LuaStandalone\LuaStandaloneInterpreter::__construct: creating interpreter: 'exec' '/bin/sh' '/home/sites/35b/2/226fa573e0/public_html/theorywiki/extensions/Scribunto/includes/Engines/LuaStandalone/lua_ulimit.sh' '7' '8' '51200' ''\''/usr/bin/lua'\'' '\''/home/sites/35b/2/226fa573e0/public_html/theorywiki/extensions/Scribunto/includes/Engines/LuaStandalone/mw_main.lua'\'' '\''/home/sites/35b/2/226fa573e0/public_html/theorywiki/extensions/Scribunto/includes'\'' '\''3'\'' '\''8'\'''

Error 127 generally means that $wgScribuntoEngineConf['luastandalone']['luaPath'] is set incorrectly,or you are otherwise missing some files in the scribunto extension.

Did you actually move the lua binary to that path?
