Package name

bcrypt

Package version

4.0.0, 4.0.1

PyPI URL

https://pypi.org/project/bcrypt/

Python version

I am aware this is the issue tracker for a Python package index specifically for Raspberry Pi

I have checked for duplicate issues

I am the maintainer

More information

Pi Zero has Raspian Buster, Python 3.7.3. uname -m gives armv6l so 32bit.

To reproduce:

$ python3 -m venv test
$ source test/bin/activate
(test) $ python3 -m pip install bcrypt==4.0.1
(test) $ python3
>>> import bcrypt
Illegal instruction

Problem happens with bcrypt 4.0.1 and 4.0.0, but does not happen with 3.2.2.

Full log (running with python3 -v):

So I removed the piwheels line from /etc/pip.conf, so that pip install bcrypt would compile it locally. (This required installing a newer rustc than the distro had.) The resulting build works -- in that I can import bcrypt without a crash.

(I originally raised this issue on bcrypt .)

I've deleted the builds - hopefully a rebuild will fix it. It'll take a while to get through all those builds but I'll keep an eye on it and will shout when it's ready.

I've just checked and it seems to be OK now -- thanks!
