Troubles with installing extentions on MediaWiki 1.35

Vasisualy2009 (talkcontribs)


I successfully installed MediaWiki 1.35 on Ubuntu 20.04 and Nginx.

But I can't install extention Echo. So, I can't both run update.php script and access web updater. More, some extensions like MobleFrontend, which don't change database, dropped my wiki to Error 500 too. What should I do? Thanks for any help!

PHP v 7.4

update.php output:

wikiadmin@wiki-ubuntu:/var/lib/mediawiki/maintenance$ sudo php update.php

PHP Fatal error:  Uncaught Exception: Unable to open file vendor/wikimedia/parsoid/extension.json: filemtime(): stat failed for vendor/wikimedia/parsoid/extension.json in /var/lib/mediawiki/includes/registration/ExtensionRegistry.php:177

Topic was marked as solved, but there wasn't described how.

I've had the same problem with MediaWiki 1.36 an Ubuntu 20.4 with Apache.

I changed wfLoadExtension( 'Parsoid', "$PARSOID_INSTALL_DIR/extension.json" );

in LocalSetting.php, which worked with MediaWiki 1.34, to

wfLoadExtension( 'Parsoid', __DIR__ . "/vendor/wikimedia/parsoid/extension.json" );

and phpupdate ran without problems.

Hope, that helps others with the same problem.

It worked also for me.

I had: wfLoadExtension( 'Parsoid', 'vendor/wikimedia/parsoid/extension.json' );

instead of

wfLoadExtension( 'Parsoid',  __DIR__ .'/vendor/wikimedia/parsoid/extension.json' );

I just had this issue while upgrading to 1.37. This solved it. Thanks.
