Can't install with "composer require"

[gbirke]

I have tried to install the library with composer require, as instructed by the README. However, I got the following error message:

Using version ^1.2 for researchgate/converter
./composer.json has been updated
Running composer update researchgate/converter
Loading composer repositories with package information
Updating dependencies
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Root composer.json requires researchgate/converter ^1.2 -> satisfiable by researchgate/converter[1.2.0].
    - researchgate/converter 1.2.0 requires researchgate/libris ^2.3.0 -> could not be found in any version, there may be a typo in the package name.

I can see that researchgate/libris is not published on packagist.org

I have tried to circumvent the error by adding the following section to my composer.json:

"repositories": [
    {
      "type": "vcs",
      "url": "https://github.com/researchgate/libris.git"
    }
  ]

This made the require command work, however while installing I got the following error messages:

Skipped branch 1.x, "9ea2294ae906b8f855ae53cde7a1ef0e5e09dc90:composer.json" does not contain valid JSON

Sorry for the late reply, this fell under the radar.
I've fixed the broken composer.json for libris 1.x and I will see about getting libris into packagist.
I'll report back next week.

Unfortunately the composer namespace researchgate/ is owned by a former employee of RG, so can't publish researchgate/libris, yet.
I've asked them to transfer ownership to us. Once that is done I'll publish libris and this should work.

Now that we have ownership, libris has been published and I've removed the now obsolete repository reference to it from the composer.json (PR #12).
I've also verified that require works now without having to specify the URL to the libris repository.
