Trying to access my ruby ​​project - LoadError related to mysql

I am trying to access my first ruby ​​project. After going to the appropriate directory and entering:

$ rails server

The following error message appears:

I previously installed gem mysql2 using RVM. I know that there is probably a simple solution, but I am new to this, so I appreciate your help.

I tried all of the above and none of them worked. I found this on another page The library is not loaded: libmysqlclient.16.dylib error when trying to start the rails server on OS X 10.6 using gem mysql2 , and it worked like a charm:

sudo ln -s / usr / local / mysql / lib / libmysqlclient.18.dylib / usr / lib / libmysqlclient.18.dylib
