I seem to have successfully installed SequenceServer.
But an error occurred while running the program. I first came into contact with SequenceServer and have no idea how to fix it.
[root@localhost /]# sequenceserver
find_spec_for_exe': can't find gem sequenceserver (>= 0.a) with executable sequenceserver (Gem::GemNotFoundException) from /usr/local/lib/ruby/site_ruby/3.2.0/rubygems.rb:282:in activate_bin_path’
