InvalidVersion on importing ytmusicapi

[khmikkelsen]

AppDaemon version: 4.1.0
HA: Supervisor 6.2 & core-2021.8.8

Importing ytmusicapi will throw InvalidVersion, possibly related to pkg_resources. My config:

system_packages:
  - libffi
  - py3-setuptools
python_packages:
  - ytmusicapi
init_commands: []

And the resulting error log:

2021-08-22 01:26:42.588304 WARNING Error: ------------------------------------------------------------

importing "hi-I-am-busy"
will also throw an error.

bu why would it be a problem from the AD addon (not even AD itself) that some unrelated packages (lib) isnt installable without extra efford??

[frenck]

This is a Python issue, there are multiple issues created around different Python projects about this.

Here are some:

• import pkg_resources triggers a DeprecationWarning on Python 3.9 pypa/packaging#368
• Remove support for LegacyVersion pypa/setuptools#2497
• import pkg_resources triggers a DeprecationWarning on Python 3.9 pypa/setuptools#2466
• Remove support for LegacyVersion pypa/setuptools#2497
• Drop LegacySpecifier and LegacyVersion pypa/packaging#407

[khmikkelsen]

I havn't been able to find references to other packages causing the same problem for AD, also this error did not only occur on python 3.9, as I had the same error on AD 4.0.8. I've only encountered this error for ytmusic api in the context of AD, which is why I took it up here first.

I'll take up the issue on the ytmusic api page instead, or perhaps pkg_resources..

[frenck]

The add-on that had AD 4.0.8 was not running Python 3.9...

[khmikkelsen]

I see.. It was just the add-on not running 3.9.

[khmikkelsen]

I found the actual issue... wheel had to be installed with system-packages.

edit: not the actual issue, but it was another issue even after forking ytmusicapi and replacing pkg_resources with importlib_resources.
