Problem installing ansible plugin

Support
1

Problem:
Istalled Foreman 3.4.1 using foreman-installer. All good. Need to install ansible plugin. Installed rubygem-foreman_ansible package from foreman-plugins repo - version 9.0.1-1.fm3_4.el8. After that foreman would not start any more. Looks like version of the plugin does not work with this setup. Removing plugin solved startup issue but I need this plugin for ansible integration. Does anybody know what version of plugin would work in this setup and where can I get it?
Expected outcome:

Foreman and Proxy versions:
Foreman 3.4.1
Foreman and Proxy plugin versions:
foreman_ansible 9.0.1
Distribution and version:
Rocky 8.7
Other relevant data:
I see following error in /var/log/nessages:
/usr/share/rubygems/rubygems/core_ext/kernel_require.rb:83:in require’: cannot load such file – rails/commands (LoadError)`

You should install the plug-in following the docs: Configuring Hosts Using Ansible

Thanks! I just ran foreman-installer command from the link you provided. I removed the rpm package from the system before running this command. There are some errors at the end of installation -

This is definitely a progress, I will see If I need to do more configuration steps!
