With the latest release of
puppet-lint and and Vox's plugins gem, a few things have changed that might cause a bit of friction when updating.
I wanted to take a second to go over a few scenarios that might help you on your journey.
First of all, lets talk about the problem.
puppet-lint v3.1.0 we adopted two plugins which are now included as default checks:
Prior to v4.0.0 of
voxpupuli-puppet-lint-plugins, these plugins were included in the meta gem.
So now we have a scenario where it's possible to update
puppet-lint (>= 3.1.0) and end up with duplicate plugins installed.
In this case, users may see warnings like this:
warning: already initialized constant PuppetLint::CheckLegacyFacts warning: previous definition of CheckLegacyFacts was here warning: already initialized constant LEGACY_FACTS_VAR_TYPES .... warning: already initialized constant TOP_SCOPE_FACTS_VAR_TYPES warning: previous definition of TOP_SCOPE_FACTS_VAR_TYPES was here
Not the end of the world, but it's extra noise that you don't want in your pipeline.
So you are seeing these warnings? Read on...
What we are seeing here is a soft dependency conflict.
We have two identical plugins registering the same code inside puppet lint. That's what is causing the
already initialized constant warning.
The best way forward is to clean up our environment and start again.
We can start by removing dependencies of
The command below will do just that. We grab the dependencies of Vox's meta gem and remove them one by one.
gem dependency voxpupuli-puppet-lint-plugins --pipe | grep "puppet-lint" | cut -d" " -f1 | xargs gem uninstall -aIx
Note: Take extra care when running commands like this! 👀
After the previous command has completed, we should be left with the
voxpupuli-puppet-lint-plugins meta gem.
Let's remove it with the following command:
gem uninstall voxpupuli-puppet-lint-plugins
..and check to see if everything has really gone.
gem list | grep "puppet-lint"
Tldr; It should return nothing! Hurrah 🎉
Now we are free to re-install puppet-lint and
gem install puppet-lint gem install voxpupuli-puppet-lint-plugins
Once they have installed you can enjoy a warning free
puppet-lint experience with all of the joys from
... unless you have linting issues!
