Gem::RemoteFetcher::FetchError: bad response Internal Server Error 500 (http://aws-eu-cache01.rubygems.org/gems/rdoc-3.12.1.gem)
An error occured while installing rdoc (3.12.1), and Bundler cannot continue.
Make sure that `gem install rdoc -v '3.12.1'` succeeds before bundling.
What I have tried:
gem install rdoc -v '3.12.1': ERROR: While executing gem ... Gem::RemoteFetcher::FetchError) bad response Internal Server Error 500 (http://aws-eu-cache01.rubygems.org/gems/rdoc-3.12.1.gem)
adding gem: --no-document to the /etc/gemrc file
adding gem: --no-rdoc --no-ri to the /etc/gemrc file
How can I get rdoc to install, or how do I get the application to install without rdoc?

Answer 1

Try reinstalling rdoc. Maybe there was a problem with the rubygems server when you last tried.
