--ignore-dependencies alternative when using bundler Gemfile

Question

We had code before to install gems:

gem install rdoc --no-document --ignore-dependencies

But after moving to bundler and Gemfile, I don't see an option to have that ignore-dependencies config.

gem 'rdoc'

The problem it is creating is , rdoc has a dependency on gem > psych , so rdoc downloads the latest version of psych. Latest version (after 5.0.0) of psych seems to break the application.

So is there a way we can ignore dependencies when using bundle and Gemfile ?

Answer 1

psych version 5 doesn't bundle libyaml which means you need to make sure you have it on your machine. If you have the option to install libyaml-dev please do it. It resolves the problem.
