`LoadError: cannot load such file` on plugin external gem

[mjsir911 (Marco Sirabella)]

Hi.

I’m trying to develop this plugin and am having issues with external dependencies.

My dependency is specified in plugin.rb with gem 'omniauth-telegram', '0.2.1' which is the
recommended way to require dependencies I believe? I’m bringing it into the docker container with this:

hooks:
  after_code:
    - exec:
        cd: $home/plugins
        cmd:
          - git clone https://github.com/mjsir911/discourse-telegram-auth.git

Results in this error:

Plugin using own gem

I am developing a plugin that needs to use an external gem, namely docx in order to generate word docs. Is there someway to do this or do I have to append it to the Gemfile?

[fzngagan (Faizaan Gagan)]

I’ve attempted a few things and made a PR to your plugin and the fix seems to be working.

FIX: require gem later
