Unable to install sanic_testing and sanic in Python 3.6
samdbmg opened this issue · comments
Hi,
It looks like sanic and sanic-testing can't be co-installed on Python 3.6, I assume because sanic 20.12 requires httpx==0.15.4 but there's no version of sanic-testing that supports a version that old?
I can apply the obvious workaround to either stop using such an old version of Python, or use "sanic_testing; python_version > '3.6'", and some conditional importing to make it work, but it might be worth dropping the 3.6 classifier from https://github.com/sanic-org/sanic-testing/blob/main/setup.py#L44 to make it more obvious it isn't going to work?
Cheers!

This also occurs for Python 3.7, where sanic installs httpx==0.19 and sanic-testing installs httpx==0.18.2

Sorry for the late reply.

In v20.12 and earlier, it is available in Sanic itself. Nothing to install, just start using app.test_client.
it might be worth dropping the 3.6 classifier
Yup. We do not support that anymore. We should get that done.
This was fixed and merged in #25
