My own environment is

The main problems we encountered earlier are: compilation is not successful, and gem is installed, but cannot be found in the GEM list.

The solution is mainly to match the gem and Ruby versions, replace the mysql version with 5.1, and install it in the rvm environment instead of using sudo.

 

Here is just a record, not detailed.
