Node couchbase module on Ubuntu server 12.04 throws "Invalid ELF header" error

Question

I'm trying to install a node app with couchbase on an Ubuntu server.

I have downloaded Couchbase and installed it from here (as listed on download page): http://packages.couchbase.com/releases/2.2.0/couchbase-server-enterprise_2.2.0_x86_64.deb

I can access it via web interface, it works fine.

Next, I try to install couchbase node module via npm:

npm install couchbase --save

This completes successfully. However when I try to run my app (which works fine on my desktop Ubuntu) I get this error:

ubuntu@aws-box:~/project/$ node index.js 

/home/ubuntu/project/node_modules/couchbase/lib/binding.js:16
  throw e;
        ^
Error:

What's going wrong?

Answer 1

Those "prebuilt" folders are put there by the package author. This is a package bug, not an npm bug. Type npm bugs couchbase to go tell them.
