Hi Sikurity, It appears that I just encountered the EXACTLY the same problem under the very similar environment with the exception of Node (perhaps Node-gyp as well) version at 0.10.10. Could you share how you fixed the issue?

It turned out to be that I had other oracle paths "E:\oracle\product\11.2.0\client_2;E:\oracle\product\11.2.0\client_2\bin" in front of the "c:\instantclient_12_1\vc10;c:\instantclient_12_1" pair. It worked once the order is reversed!

Oh.... Thank you for your HELP!!

This just helped me as well! After I installed Oracle Express, it altered my path and messed up my original changes described in the INSTALL.md.

Thanks for point me in the right direction!

I have a same problem. My error:
