Installation of oracle - Failed with error "Binary operator expected"

[sivamsailaja]

While trying to run "npm install oracle" it is failing to install with the below error. Is this because of node and node gyp version? How to get the node gyp for the installed node version?

npm install
npm http GET https://registry.npmjs.org/oracle
npm http 304 https://registry.npmjs.org/oracle

oracle@0.3.6 install /Users/s3kota/Documents/columbuscheckout/columbus/node_modules/oracle
node-gyp rebuild
