Module Thesaurus install problem

I get a “Call to undefined method Thesaurus\Module::installDir() …/modules/Thesaurus/Module.php:73” error when trying to install module Thesaurus 3.4.11 @Daniel_KM

I raised an issue on Github too.
Did this before I saw someone else raised this issue (since 3days) on Gitlab

Greetings, John.

P.S. after removing the call in line 73, the module seems at least too install fine. I didnot check its workings yet.

Thanks, it is fixed in 3.4.12.
