uninitialized constant Syck (NameError) about kitchen-docker HOT 7 CLOSED

Looks like an issue with a transitive dependency. Have use tried with a
2.1.x version?

Ruby is pretty bad when it comes to dependency conflicts and version
upgrades

I have exactly the same problem with ruby 2.2.2, but no problems with ruby 2.1.6

from kitchen-docker.

Ah found out what the problem is, see http://ruby-doc.org/stdlib-2.2.2/libdoc/yaml/rdoc/YAML.html.

Syck was the original for YAML implementation in Ruby’s standard library developed by why the lucky stiff.

You can still use Syck, if you prefer, for parsing and emitting YAML, but you must install the ‘syck’ gem now in order to use it.

In older Ruby versions, ie. <= 1.9, Syck is still provided, however it was completely removed with the release of Ruby 2.0.0.

So you now have to install the Syck gem

from kitchen-docker.

I am able to run with 2.2.2. Looking at the stack trace, it seems that
there is a gem file on your system that is not compatible with Test
Kitchen. Maybe run with bundler to ensure the correct gem versions are used.

bundle install --path vendor/bundle
bundle exec kitchen test

This repo for some reason has an excludes on the Gemfile.lock which should
really be commited to lock the versions of any gem dependencies, and then
this avoids the situation where other gems already installed cause a
failure.

UPDATE: Just seen your follow up. I have not had to install the Syck gem to get it running with 2.2.2

from kitchen-docker.

After some extra testing, if you use the Gemfile to load/install the required dependencies, the syck gem gets pulled in automatically, instead of relying on what is or is not on your existing GEM_PATH location.

+1 with ruby 2.2.1 using bundler

Closing issue due to inactivity. Please open a new issue if there is still a problem. Thanks!
