Error Message:
Set the environment variable ORACLE_HOME if Oracle Full Client.
Append the path of Oracle client libraries to LD_LIBRARY_PATH if Oracle Instant Client.

Answer 1

The ruby-oci8 gem needs the Oracle client libraries to compile. According to the error message:
Error Message:
Set the environment variable ORACLE_HOME if Oracle Full Client.
Append the path of Oracle client libraries to LD_LIBRARY_PATH if Oracle Instant Client.
your ORACLE_HOME environment variable is not set, nor can it find the needed libraries in LD_LIBRARY_PATH.
Make sure that your have either Oracle Full Client or Oracle Instant Client installed and properly set, and try again.
