Could not determine home directory.

Hi,

I'm using httpx in a docker container where the executing user is dictated from the outside (Jenkins) and no HOME environment variable is available.

I'm getting an exception in this case:

Traceback (most recent call last):
 File "/tmp/.venv/bin/httpx", line 8, in <module>

 File "/usr/local/lib/python3.10/pathlib.py", line 1440, in expanduser
   raise RuntimeError("Could not determine home directory.")
RuntimeError: Could not determine home directory.

Way to reproduce:

$ docker run -u 123 -t -i python:3.10 bash
> cd /tmp/
> python3 -m venv .venv
> .venv/bin/pip3 install httpx[cli]
> env -i .venv/bin/httpx http://github.com

• The env -i clears all environment variables.
• I run it directly with python (not the CLI) but the result is the same and so it is easier to reproduce.

I know it's not a common issue, anyhow, I think it is easy to catch this in httpx.

Works without issues like this:

                         self._netrc_info = netrc.netrc(str(expanded_path))

Are you interested in a PR for this?

Thank you for raising this.

I believe this is a duplicate of #2526, which has been resolved by #2535 - so this should be fixed in the next release.

You could try installing directly from GitHub in order to verify this...

$ pip install git+https://github.com/encode/httpx

Thank you for the quick reply. It works for me in the mentioned version. 👍
