For a plugin that I am writing, I would like to use some external gem files that are not present in the default discourse gemfile.
What is the standard way of doing this without being able to modify the discourse gemfile?
Also a similar question reqarding user-defined rake tasks.
https://github.com/xfalcox/discourse-backups-to-dropbox/blob/master/plugin.rb#L7
Keep in mind you have to declare the gems AND dependencies.
Thanks, didnât realize that all dependencies needed to be included as well.
How can I also do this for rake tasks?
Have you tried âLOAD_PLUGINS=1 rake your:rake:taskâ?
I am trying to use this ruby gem called oxford_dictionary
gem 'oxford_dictionary', '2.0.1', { require: false }
This is what I get in the console
/bin/bash -c "env RBENV_VERSION=2.6.2 /usr/local/Cellar/rbenv/1.1.2/libexec/rbenv exec ruby /Users/faiz/discenv/discourse/bin/rails server -b 0.0.0.0 -p 3000 -e development"

I think its probably because of discourse not being able to install a dependency required by the gem itself. How do I fix this?
Update
Ok I fixed it. Its dependency called plissken had to be mentioned separately.
Why is that though?
Your target gem has a dependency thatâs not included in the main Gemfile so you need to include it in plugin.rb
This can be a lengthy iterative process sometimes!
I would say a lengthy recursive process 
Also, I cannot use require: false there. I have to make it true and explicitly require it to make it work.
Wish that recursion could be handled by the computer one day 
Based off my own exp, an update:
I am not sure what ârequiredâ does but I set it to true
Hey, I know this was a while ago, but I am trying to install the eth gem and its failing on a dependency with this error:

I have required the forwardable dependency, among a few others just in case (which I got from my Gemfile.lock), but my app just canât rebuild without throwing this error, any ideas?
