Remove openssl from your Gemfile and delete it from your gems

anyone can help me please?

It’s telling you that you installed openssl installed as a gem which is
a system binary and library. Remove that line from your Gemfile and run
bundle again to rebuild your gemset. It should get rid of the error
when launching rails server or rails s.
