Hi I'm installing a fresh copy of this plugin over my docker instance and I'm getting:

This is due to this: https://github.com/yaml/pyyaml/issues/476

Probably we can enforce the correct version (5.4) here to fix

Note: I'm also getting:


Requirement already satisfied: python-slugify>=1.0 in /usr/lib/python2.7/site-packages/python_slugify-5.0.2-py2.7.egg (from ckanapi->ckanext-scheming==2.1.0) (5.0.2)
ERROR: Package 'python-slugify' requires a different Python: 2.7.18 not in '>=3.6'

That could be solved with:

pip install python-slugify==4.0.1

But I'm not sure from which package/plugin it comes (already provided), could it be the core?

I also had to do 

install_requires=[
-        'pyyaml',
+        'pyyaml==5.4',

I think we can set pyyaml<=5.4
