Error: libcouchbase.so.2: cannot open shared object file: No such file or directory

I am using Ubuntu14.04LTS. I have created an application using NodeJS and Couchbase as a backend, which is perfectly running on my laptop. When I tried to run the same on my other laptop, it is throwing the following error:

/home/satyam/projects/maya-api/node_modules/couchbase/node_modules/bindings/bindings.js:79

What could be the wrong? Any kind of suggestion will be appreciated.
Thanks in advance!..
