v1.7.0 from v1.6.0 introduces a rustls version conflict preventing v.1.7.0 from compiling

[EdmundsEcho]

Bug Description

I did not fix my maturin version in a github action that installs maturin. My github action started to fail using maturin v1.7.0 where it was working with v1.6.0. I'm confident it is a maturin issue as my pyo3 code does not depend on rustls (see the error below). I have encountered this version conflict with rustls in other projects so know how it can creep-in to the build process.

In the github action we use: pip install maturin. This is not the case on my desktop where the project compiles using the previous version of maturin.

Finally, I made sure to use a github action that cleared any caches. This might still be an issue. I'll be sure to update the issue when I resolve the issue.

Your maturin version (maturin --version)

1.7.0

Your Python version (python -V)

3.11

Your pip version (pip -V)

unsure (likely not relevant)

What bindings you're using

pyo3

Does cargo build work?

• Yes, it works

If on windows, have you checked that you aren't accidentally using unix path (those with the forward slash /)?

• Yes

Always use cargo install --locked maturin when building from source.
