Thanks I'll try that

This worked and I've reinstalled all the builders with it. Please flag any package versions that need rebuilding and I'll kick them off again.

Yeah it didn't work in the end. One of the commits changed it to install as root, not for the piwheels user. I tried copying `.cargo` to `/home/piwheels/` but that...

I'm really confused now. I can successfully build it as the piwheels user:  but it still fails when built during the automated piwheels build process: https://piwheels.org/logs/0000/0894/1395.txt...

While rustc in Bullseye is sufficient for some builds now - it'll soon slip behind and not be suitable as projects demand newer rust over time!

That's very strange. I tried swapping `--abi cp37m` to `--python-version 3.7` and that worked. Will do further investigation. Thanks for the heads up.

Adding `-vvv` (maximum verbose) shows the file `MarkupSafe-2.1.1-cp37-cp37m-linux_armv7l.whl` being skipped: ``` Skipping link: none of the wheel's tags (cp37-cp37m-linux_armv7l) are compatible (run pip debug --verbose to show compatible tags): https://www.piwheels.org/simple/markupsafe/MarkupSafe-2.1.1-cp37-cp37m-linux_armv7l.whl#sha256=04ecce2077c9c531334c847b604835e8e909f73d1fe596ceae30c8046ca90686...

Oh, you have been using the wrong `platform` value. It should be `linux_armv7l` not `linux_arm7l`. But still, swapping `--abi cp37m` for `--python-version 3.7` makes a difference: ```console (piptest) fern:~ $...

No - see: - https://github.com/piwheels/packages/issues/119 Also see https://www.piwheels.org/faq.html > Which Python versions does piwheels support? > piwheels supports Python 3 only. While most packages available will work in any version...
