Great, thank you for confirming. I’ll make a new release tomorrow.
Okay, this is fixed in #172.
Please could those experiencing this problem @daniel-butler @br3ndonland @gravy-jones-locker try this and confirm it fixes the problem for you.
To install from wheel from the PR:
pypi_filesfrom the CI runpip install pypi_files/watchfiles-0.0.0-cp37-abi3-manylinux_2_12_x86_64.manylinux2010_x86_64.whlmissed the notifications for these. but the immediate issue is definitely fixed. thanks!
It is working for me when I use the updated wheel! Thank you for fixing!
Okay, I can reproduce this.
First the good news:
--platform linux/amd64force_polling=TrueIt might also be worth honouring an env variable to enable polling for those who are using watchfiles via a third party library and therefore aren’t able to use the kwarg directly.
In terms of the underlying error and how to handle it, I’m not really sure where to go.
@messense do you have any ideas?
