There was an error while loading `nextcloud-deck-api.gemspec`: cannot load such file -- dry-struct

Hi!

I am in the process of writing my first gem.

Trying to use Travis CI to automatically run tests and lint the code (and then hopefully later deploy), I am running into the following failure of my builds:

bundle exec rake install

[!] There was an error parsing `Gemfile`: 

[!] There was an error while loading `nextcloud-deck-api.gemspec`: cannot load such file -- dry-struct

Does it try to require a relative path? That's been removed in Ruby 1.9. Bundler cannot continue.

 #  from /home/travis/build/Pamplemousse/nextcloud-deck-api.gem/nextcloud-deck-api.gemspec:5

 #  -------------------------------------------

 #  $LOAD_PATH.unshift(lib) unless $LOAD_PATH.include?(lib)

 >  require 'nextcloud-deck-api'

 #  

 #  -------------------------------------------

. Bundler cannot continue.

 #  from /home/travis/build/Pamplemousse/nextcloud-deck-api.gem/Gemfile:5

 #  -------------------------------------------

 #  

 >  gemspec

 #  -------------------------------------------

The command "bundle exec rake install" failed and exited with 14 during .

Here is the complete build log: https://travis-ci.org/github/Pamplemousse/nextcloud-deck-api.gem/builds/709364716 .

I hopelessly cannot understand why bundle exec rake install (or bundle install for that matter) do not run successfully in the CI, while I don’t seem to have any problems on my machine…

Here is the code of the failing build: ; And of particular interest, the Gemfile, .gemspec, and .travis.yml.

Thanks for your help :slight_smile:
