Error: Cannot find module './build/Debug/buffertools.node

We upgraded to Node 6.9.1 and started getting the following error when running our application when we require buffertools. We're using version buffertools 2.1.4.

buffertools/buffertools.js:

try {
        var buffertools = require('./build/Release/buffertools.node');
} catch (e) {
        var buffertools = require('./build/Debug/buffertools.node');
}

The statement in the catch block is line 26. It's looking for the buffertools.node file in /u01/app/myappapps/myapp/src/myapp/node_modules/buffertools/build/Release and that file is there.

It turns out that there was an exception due to a Node.js version mismatch. I suggest adding a log statement to that catch block.

Not a bad idea. Done in 1648d39, released in v2.1.5.
