Package with binary npm dependency

help
1

Hi,

I am making an unpublished package that uses exiv2 npm’s binary module. It used to work fine on my project, but when cloning my project on a new linux machine I get the following error, and noticed that the npm_modules directory is not created in my package directory, but present on my other linux machine.

I could copy npm_modules from my other machines, but I would appreciate to understand what is it I am doing wrong.

Below are the error I get and my package.js file.

My package.js file looks like this:

Package.describe({
     ...
});

Npm.depends({
    "imagemagick": "0.1.3", 
    "exiv2": "0.4.1",
    "fibers":"1.0.1"
});

Package.on_use(function (api) {
    api.export('Lightroom');
    api.add_files("lightroom.js", ["server"]);
});

Maybe you need to install libexiv2 on your computer (like the error says).

Whoops, Thanks for you reply. Though I still need some advice about the following steps that I had to do to make it work.

The error I got next was the following:

Error: Cannot find module './build/Release/exiv2.node'

The Release folder was indeed not created, and I had to build the exiv2.node module myself by executing node-gyp rebuild in the .meteor/local/isopacks/williamledoux_lightroom/npm/node_modules/exiv2 directory of my application.

So the question is: Is there a way I could embed the binary builds of this npm package in my meteor package so that users (and future myself) don’t have to follow those steps ?

When you publish a package with native dependencies, Meteor will prompt you a message that you need to build the package for each architecture by using the build machines. It’s the meteor build-for-arch <PACKAGE_NAME>@<PACKAGE_VERSION> command.

All npm packages that have a binding.gyp file are treated as npm packages with native dependencies.
