I'm installing ruby 3.3.x with rvm by rvm install 3.3.5, no apparent error shown. However, I noticed psych gem folder is empty,even though it's there in the gem list as psych 5.1.2. this causing problems when I try to gem install/uninstall anything, since it keeps saying, cannot load file --psych. Any ideas how to fix this issue please. Thanks in advance.
