   Here's the same thing slimmed down to just an httpcore example...

   example.py

   import httpcore
   import asyncio
   
   
   async def main():
       async with httpcore.AsyncConnectionPool() as pool:
           response = await pool.request("GET", "https://www.example.com")
           print(response)
   
   
   asyncio.run(main())

   console:

   $ python3 -m venv venv
   $ venv/bin/pip install httpcore[asyncio]
   $ venv/bin/pip uninstall anyio
   $ venv/bin/python example.py
   Traceback (most recent call last):

       raise RuntimeError(
   RuntimeError: Running with asyncio requires installation of 'httpcore[asyncio]'.
   
   During handling of the above exception, another exception occurred:
   
   Traceback (most recent call last):

       await self._anyio_lock.acquire()
   AttributeError: 'AsyncLock' object has no attribute '_anyio_lock'

   This is okay... can see an appropriate RuntimeError when we deliberately break the installation, but it could be neater.

   ---

   edit:

   A better replication of this...

   $ python3 -m venv venv
   $ venv/bin/pip install httpcore  # Intention was to install `httpcore[asyncio]`
   $ venv/bin/python example.py
