Resolving dependencies...
Bundler could not find compatible versions for gem "dry-types":
In snapshot (Gemfile.lock):
dry-types (= 0.12.3)
In Gemfile:
hanami (~> 1.3) was resolved to 1.3.3, which depends on
hanami-validations (>= 1.3, < 3) was resolved to 1.3.5, which depends on
dry-validation (~> 0.11, < 0.12) was resolved to 0.11.2, which depends
on
dry-types (~> 0.12.0)
hanami-model (~> 1.3) was resolved to 1.3.2, which depends on
dry-types (~> 0.11.0)
Running `bundle update` will rebuild your snapshot from scratch, using only
the gems in your Gemfile, which may resolve the conflict.
ERROR: Service 'app' failed to build: The command '/bin/sh -c bundle install' returned a non-zero code: 6
というエラーになる。どうやらhanami-validationsとhanami-modelが依存しているdry-typesのバージョンが異なるらしい。ので~> 0.11.0をあらかじめ指定したらうまくいった。
