PyYAML==3.13 failed to install

[asavaritayal]

If the requirements.txt contains PyYAML==3.13, the following error is received when publishing the function app -

Could not find a version that satisfies the requirement PyYAML==3.13 (from versions: )
No matching distribution found for PyYAML==3.13

ERROR: binary dependencies without wheels are not supported

The wheel error is odd since it seems that PyYAML indeed does offer wheel packages for version 3.13. See here - yaml/pyyaml#49

@elprans can you please investigate this?

[elprans]

@asavaritayal It only offers wheels for Windows, but not for Linux, which is a target platform.

[asavaritayal]

Thanks for confirming! @elprans so in the future I can check myself, is there a way to determine from PyPI whether a package offers linux wheels or not?

[asavaritayal]

Ah, never mind. I figured it out. Thanks :)
