"Error: unable to load libxl.node" doesnt show real problem

[i4got10]

Im trying to find the reason why lib not working and add console.log to watch that going wrong

for (var i = 0; i < paths.length; i++) {
    try {
        bindings = require(path.join(paths[i], 'libxl'));
        break;
    } catch (e) {
        console.log(e);
    }
}

first is that paths is [ undefined ], so we can pass it with

var paths = process.env['NODE_LIBXL_PATH'] ? [process.env['NODE_LIBXL_PATH']] : [];

second it could be better to show the truth reason of library fail

        if (e.code !== 'MODULE_NOT_FOUND') {
            throw e;
        }

LOGS

[TypeError: Arguments to path.join must be strings]

Hi Alexey!

Thanks for spotting the glitch in the handling of the environment variable, I fixed it. As for the other change you the suggest, I see the problem, but I would prefer a more robust solution that still tries to exhaust all possibilities before failing. Any suggestions? Otherwise, I'll try to think about something a bit more robust later when I find time ;)

Cheers -Christian

Thanks Christian! Its just a suggestion from my side.

y cual es la solución?

@DirtyHairy I am confused what is the solution for this too. I am getting the "image not found" error.

I am assuming that "image not found" error is referring to not being able to find /node_modules/libxl/deps/libxl/lib/libxl.dylib. That file does exist though.

require('/Users/gajus/Documents/dev/[..]/node_modules/libxl/build/Release/libxl.node');

libxl.dylib needs to be copied to the current working directory or path to libxl.dylib must be added to DYLD_LIBRARY_PATH.

Upon second reading, this is clearly explained in https://github.com/DirtyHairy/node-libxl#compilation-phase
