I am trying to come back to create another application on Rail4 and When I try to start the application this is what happened:

    prompt$ rails server

   prompt$

I read all the 'Rails Server Error' posted previously here and tried most of the solution offered here but none of them worked for me.

I am thinking that maybe is the file dlopen what I am missing.

I will appreciate any help please

    yeah, your mysql database is not properly installed – Lukasz Muzyka Mar 30 '17 at 05:14

You need to reinstall your mysql library. Then:

gem uninstall mysql2

bundle install

To rebuild the gem against the new mysql library
