anyconfig does not load yml files

[JoshZastrow]

I have an example credentials.yml file stored in my project folder conf/local

config/local/credentials.yml

dev_s3:
    aws_access_key_id: token
    aws_secret_access_key: key

Which I verified in a python session:

Python 3.8.3 (v3.8.3:6f8c8320e9, May 13 2020, 16:29:34) 
[Clang 6.0 (clang-600.0.57)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import os
>>> import anyconfig
>>> anyconfig.__version__
'0.9.11'
>>> f = 'config/local/credentials.yml'
>>> os.path.exists(f)
True
>>> from pathlib import Path
>>> fpath = Path(f)
>>> f
'config/local/credentials.yml'
>>> fpath
PosixPath('config/local/credentials.yml')
>>> with open(f, 'r') as fobj:
...     for l in fobj: print(l)
... 
dev_s3:

    aws_access_key_id: token

    aws_secret_access_key: key

However, anyconfig cannot load this file using the load function as suggested in the docs:

I did try with the absolute path, which made no difference. Aren't yml's processed by anyconfig?

Is PyYAML installed in your environment? If not, anyconfig cannot load YAML data.

Ah great -- much appreciated! Didn't realize I needed to install that package separately.

That's good ;-)

Although the doc has a note about it (https://github.com/ssato/python-anyconfig#supported-configuration-formats), maybe it needs some updates and/or fixes. Thanks for your report making me notice about that!
