A stripped down example of an issue I've been seeing with pyo3, asyncio, and rust async-std. It's unfortunately a tricky problem.
- Install Docker
sudo apt-get install docker.io
- Add your user to the docker group
sudo usermod -aG docker $USER - Reboot
sudo reboot
- Test Docker CE
docker run hello-world
sudo apt-get install make
Run scripts/test.sh from the project directory. It should build the docker environment and run the test for you.
scripts/test.sh
If you see what I see, then the test itself should pass, but the process should exit with an error similar to this:
pyo3-issue$ scripts/test.sh
make: '.make/pyo3-issue-dev' is up to date.
