custom_require.rb:36:in `require’: cannot load such file – oci8 (LoadError)

my code is here.

require ‘oci8’
oci =‘user’,‘pass’,‘ip:port/sid’)

oci.exec(‘select * from table’) do |record|
puts record.join(’,’)

Pls help me. What’s wrong ?


Hi Tsolmon,

Yes i installed ruby-oci8 from source.

ruby setup.rb config – --with-instant-client

mnts26@mnts26:~/Downloads/ROR OCI8/ruby-oci8-2.0.4$ make

ruby -w setup.rb config

Try ‘ruby setup.rb --help’ for detailed usage.

I got those lines.


Installation failed due to error

For installing that ruby-oci8 gem u need
1. instantclient-basic
2. instantclient-sdk
3. u need to export LD_LIBRARY_PATH of that path
4. then run bundle install
