Trouble installing ruby-oci8 gem

I'm trying to install a gem ruby-oci8 on the rails.

I get the following error,

$ gem install ruby-oci8

To see why this extension failed to compile, please check the mkmf.log which can be found here:

  /home/solovievga/.rvm/gems/ruby-2.4.2/extensions/x86_64-linux/2.4.0/ruby-oci8-2.2.5.1/mkmf.log

extconf failed, exit code 1

Gem files will remain installed in /home/solovievga/.rvm/gems/ruby-2.4.2/gems/ruby-oci8-2.2.5.1 for inspection.

I wonder how I can install the ruby-oci8 package?

I have a similar problem installing the ruby-oci8 gem. In my case, there is already an app that uses it. When I deployed another app using the same gem, during bundle install, this error occurred. It asked for the LD_LIBRARY_PATH environment variable. Apparently, the installer of the old app did not set the variable to persist.

I thought that there should be an oracle library somewhere in the server so I searched for it. It was not in /opt but in /usr/lib. I set the variable to /usr/lib/oracle/11.1/client64/lib then the gem was installed smoothly.

This solution worked for me

Before executing bundle install, Run below code on the console or add it to bash and source.

Export OCI_DIR=/opt/oracle/instantclient_12_2

Here /opt/oracle/instantclient_12_2 is path to instantclient on my mac machine.

You need to download instantclient from https://www.oracle.com/database/technologies/instant-client/downloads.html Unzip the download into /opt/oracle directory and export OCI_DIR environment variable.

These steps take you through the instant client installation process as well, just to provide some context. Download the instant and SDK zip files here:

http://www.oracle.com/technetwork/topics/linuxx86-64soft-092277.html

Unzip both files in the following directory as root.

/opt/oracle

Enter the instantclient_12_2 directory following the unzip and create a symlink for the libclntsh.so file:

ln -s libclntsh.so.12.1 libclntsh.so

Now, depending on your OS, you'll need to update your LD_LIBRARY_PATH location. In Ubuntu, do the following:

sudo nano /etc/ld.so.conf.d/moreLibs.conf

And enter the following in the file and save

/opt/oracle/instantclient_12_2

Now run the following command:

sudo ldconfig

And rerun your gem install

gem install ruby-oci8

You have to set LD_LIBRARY_PATH to install ruby-oci8 gem. Here I am assuming you are using linux os. Try this on your terminal.

$ LD_LIBRARY_PATH=$ORACLE_HOME/lib
$ export LD_LIBRARY_PATH
$ gem install ruby-oci8

Edit:

If you uses mswin32 ruby, use the following command instead.

gem install --platform x86-mingw32 ruby-oci8
  or
gem install --platform x64-mingw32 ruby-oci8

Let me know If you have any query or question.

Happy Coding
