Requiring external gems

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.

Keep in mind you have to declare the gems AND dependencies.

Thanks, didn’t realize that all dependencies needed to be included as well.

How can I also do this for rake tasks?

Have you tried “LOAD_PLUGINS=1 rake your:rake:task”?

Sto cercando di utilizzare questo gem di Ruby chiamato oxford_dictionary

gem 'oxford_dictionary', '2.0.1', { require: false }

Questo è ciò che ottengo nella 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"

Processo terminato con codice di uscita 1

Penso che sia probabilmente dovuto al fatto che Discourse non riesce a installare una dipendenza richiesta dal gem stesso. Come posso risolvere?

Aggiornamento
Ok, l’ho risolto. La sua dipendenza chiamata plissken doveva essere menzionata separatamente.
PerchÊ è cosÏ, però?

Il tuo gem target ha una dipendenza che non è inclusa nel Gemfile principale, quindi devi includerla in plugin.rb.

A volte questo può essere un processo iterativo lungo!

Direi che è un processo ricorsivo piuttosto lungo :rofl:

Inoltre, non posso usare require: false lĂŹ. Devo impostarlo su true e richiederlo esplicitamente per farlo funzionare.

Spero che un giorno la ricorsione possa essere gestita dal computer :stuck_out_tongue_winking_eye:

Basato sulla mia esperienza, un aggiornamento:

  • SĂŹ, il numero di versione è obbligatorio
  • Per ottenere queste dipendenze, installa Ruby 2.6.5 (la versione di Ruby attualmente utilizzata da Discourse) sul tuo computer locale e crea un file Gemfile con i gem che desideri.
  • Esegui “bundle install” nel terminale per creare Gemfile.lock
  • Questo elenca tutti i gem, le dipendenze dei gem e i numeri di versione.
  • Fai come nota Rafael in plugin.rb

Non sono sicuro di cosa faccia ‘required’, ma l’ho impostato su true

Ehi, so che è passato un po’ di tempo, ma sto cercando di installare la gemma eth e fallisce a causa di una dipendenza con questo errore:

Il mio repository è qui: GitHub - JD0x2e/discourse-radiant-member: Get member status and update group membership

Ho richiesto la dipendenza forwardable, tra le altre per sicurezza (che ho preso dal mio Gemfile.lock), ma la mia app non riesce a ricostruire senza generare questo errore, hai qualche idea?
