ERROR: ActiveRecord oracle_enhanced adapter could not load ruby-oci8 library. Please install ruby-oci8 gem #40

Closed alexvaigm closed 11 years ago

alexvaigm commented 11 years ago

I installed new rails app with oracle database I have installed rails v4, ruby v2, ruby-oci8 v2.1.5

I am working on Win7 64bit

When I starting rails server I am getting error:

ERROR: ActiveRecord oracle_enhanced adapter could not load ruby-oci8 library. Please install ruby-oci8 gem

kubo commented 11 years ago

Does the following command work?

ruby -e "require 'oci8'"

If it works, could you add "(#$!)" to the error message in oracle_enhanced_oci_connection.rb as follows and kick rails server again?

begin
  require "oci8"
rescue LoadError
  # OCI8 driver is unavailable.
  raise LoadError, "ERROR: ActiveRecord oracle_enhanced adapter could not load ruby-oci8 library. Please install ruby-oci8 gem. (#$!)"
end

after I added like you said I got:

LoadError (ERROR: ActiveRecord oracle_enhanced adapter could not load ruby-oci8 library. Please install ruby-oci8 gem. (cannot load such file -- oci8)):

kubo commented 11 years ago

ruby -e "require 'oci8'" raised no error and require 'oci8' in rails server raised 'cannot load such file -- oci8'. It is correct?

If so, ruby in command line and ruby used by rails may have different $LOAD_PATH. Could you post the output of the following commands?

gem list
bundle list

yes , it is correct.

my Gemfile starting with:

source 'https://rubygems.org' gem 'rails', '4.0.0' gem 'ruby-oci8' gem 'activerecord-oracle_enhanced-adapter'

I managed to overcome the error "cannot load such file -- oci8", by compiling ruby-oci8-2.1.5 source using make and make install

now I have a new error:

undefined method arel_attributes_values' for classActiveRecord::Base'

kubo commented 11 years ago

I'll close this issue because the new error isn't related to ruby-oci8. It is filed as an oracle_enhanced adapter issue. See rsim/oracle-enhanced#312.
