Starting rails dev server results in cannot open shared object file: No such file or directory puma_http11.so (LoadError)

Question

I'm trying to start rails server (puma) using command rails s

I get this error:

rails s I, [2017-11-16T10:47:05.872867 #16905] INFO -- sentry: ** [Raven] Raven 2.5.1 configured not to capture errors: Not configured to send/capture in environment 'development' => Booting Puma => Rails 5.1.3 application starting in development on http://localhost:3000 => Run rails server -h for more startup options Exiting /home/mariusz/.rbenv/versions/2.4.1/lib/ruby/gems/2.4.0/gems/activesupport-5.1.3/lib/active_support/dependencies.rb:292:in require': libssl.so.1.0.2: cannot open shared object file: No such file or directory - /home/mariusz/.rbenv/versions/2.4.1/lib/ruby/gems/2.4.0/gems/puma-3.10.0/lib/puma/puma_http11.so (LoadError) from /home/mariusz/.rbenv/versions/2.4.1/lib/ruby/gems/2.4.0/gems/activesupport-5.1.3/lib/active_support/dependencies.rb:292:in block in require'

My project info: puma (3.10.0), rails (5.1.3), ruby 2.4.0

Answer 1

The problem was with invalid environment. I needed to restore all my gems to pristine state. Running gem pristine --all helped. (it takes about 10 min to finish it)

Answer 2

I solved the problem this way. Go to the tmp/pids folder then in the server.pids file erases the content of this file. The content is the pid of the server rails execution process.
