Rails server and console fails to start : “cannot load such file — zip/zip (LoadError)”

Question

My development server has worked fine for years. Today, perhaps due to some update in bundler version, both server and console have started to fail when launched.

I really have not a clue of what might be wrong. It seems that some gems have been updated:

Answer 1

Docs

The Rubyzip interface has changed!!! No need to do require "zip/zip" and Zip prefix in class names removed.

If you have issues with any third-party gems that require an old version of rubyzip, you can use this workaround:

gem 'rubyzip', '>= 1.0.0' # will load new rubyzip version gem 'zip-zip' # will load compatibility for old rubyzip API.

So I assume "for years" means you'd have been using the old rubyzip api. So add the zip-zip gem and you should be fine.

Answer 2

Add rb-readline in your Gemfile and try to run rails server. If it doesn't work do sudo apt-get install libreadline-dev and repeat the process.
