Module did not self-register

I'm attempting to use node-tika in a project that builds/tests via CircleCI. Their CI environment installs various things for me, but when my server attempts to start it fails as follows:

[17:54:45] Using gulpfile ~/ow-back/gulpfile.js

CircleCI appears to be running ubuntu, and JAVA_HOME=/usr/lib/jvm/jdk1.7.0 to give you a sense of my java version.

It appears this is some kind of java incompatibility issue, but what are the troubleshooting steps associated with fixing this?

[moxious]

From my packages.json: "tika": "^1.3.0"

[moxious]

Extremely suspicious about this, note the error message references /home/ubuntu/ow-back/node_modules/tika/node_modules/java/lib/nodeJavaBridge.js. In my local dev installed copy of node-tika, that file doesn't exist. Is it possible it's using a wrong version somehow?

Hi @moxious, did you ever solve this issue in the end?

[moxious]

I never got to the root cause. I did solve it through a mixture of downgrading node, upgrading java, and removing node_modules but I was never sure what actually did it.
