SoCo 0.22.0 fails to install on some platforms due to requirement to build 'yarl' and 'mutlidict'

[pwt]

The inclusion of events_asyncio in v0.22.0 brought in a dependency on the aiohttp package, which in turn depends on yarl and multidict.

It turns out that both yarl and multidict have binary wheels, with prebuilt versions available for some platforms (Linux, macOS, Windows), meaning that installs on these platforms will work without error.

However, build/installation failures can occur on other platforms, including on Raspberry PIs running PiOS (Raspbian). In order to install successfully, the build-essential (compiler, etc.) and python3-dev (Python headers) packages must be present:

sudo apt install build-essential python3-dev

These new dependencies may also cause install failures on other platforms.

We need to determine whether this is going to be a major problem, and look for workarounds.

@bdraco : Do you have any thoughts on this? I'm worried that the inclusion of the new aiohttp dependency is going to prevent SoCo installs on some platforms.

[bdraco]

How about making it an extra? so you can do something like

pip install 'SoCo[asyncio]'

extras_require = {
'asyncio': ['aiohttp']
}

Typing this on a mobile so hopefully it makes sense.

Also FWITW, both yarl and multidict have pure python install options and can be installed as follows:

MULTIDICT_NO_EXTENSIONS=1 pip install multidict
YARL_NO_EXTENSIONS=1 pip install yarl

I think the extra route is the safer one though

Great -- thanks @bdraco.

I'll have a play with removing the hard requirement, and the extras_require approach.
