I am in the middle of upgrading our project to Ruby v2.7 and have a trouble with couchbase-ruby-client gem. The bundling process went fine, however I am getting LoadError: cannot load such file – yaji/2.7/parser_ext at runtime.
It seems that this comes from yaji dependency which was resolved to v0.3.5. The latest parser_ext.so file in this version of gem is for Ruby v2.1. I believe this project is also maintained by your company, am I right? Could you update it, so everything could work again with latest Ruby?
