Hi everyone!
I'm trying to contribute to the cryptography project but I have some trouble setting up the project. I try to follow the *Getting started* page but the command *nox -e tests -p py310 *don’t succeed. Here are all the commands I run (I'm on a Mac M1) : git clone https://github.com/pyca/cryptography.git virtualenv cryptography source cryptography/bin/activate cd cryptography pip install nox nox -e tests -p py310 My first problem is that this last command does not work and gives me this error message: nox > Python version selection caused no sessions to be selected. But I do have python 3.10 installed. Then I tried to run *nox -e tests. *This command works at first but then I have an error message that I don’t understand (it’s at the end of the message if you need it). I tried to run manually the command *python -m pip install -v -c ci-constraints-requirements.txt '.[test]' *and it works. I don’t understand why it works when I run it manually but not when the script runs it. Thanks for your help, Jules This is I think the most interesting part of my error message (I can send you more if needed) : Caused by: process didn't exit successfully: `rustc --crate-name vcpkg /Users/jules/.cargo/registry/src/index.crates.io-6f17d22bba15001f/vcpkg-0.2.15/src/ lib.rs --error-format=json --json=diagnostic-rendered-ansi,artifacts,future-incompat --crate-type lib --emit=dep-info,metadata,link -C embed-bitcode=no -C debug-assertions=off -C overflow-checks=on -C metadata=4128c5710ab69439 -C extra-filename=-4128c5710ab69439 --out-dir /Users/jules/Documents/cryptography/src/rust/target/release/deps -L dependency=/Users/jules/Documents/cryptography/src/rust/target/release/deps --cap-lints allow -Cinstrument-coverage` (exit status: 1) error: `cargo rustc --lib --message-format=json-render-diagnostics --manifest-path src/rust/Cargo.toml --release -v --features pyo3/extension-module --crate-type cdylib -- -C 'link-args=-undefined dynamic_lookup -Wl,-install_name,@rpath/_rust.abi3.so'` failed with code 101 *error*: *subprocess-exited-with-error* × Building wheel for cryptography *(*pyproject.toml*)* did not run successfully. │ exit code: *1* ╰─> See above for output. *note*: This error originates from a subprocess, and is likely not a problem with pip. *full command*: /Users/jules/Documents/cryptography/.nox/tests/bin/python /Users/jules/Documents/cryptography/.nox/tests/lib/python3.11/site-packages/pip/_vendor/pyproject_hooks/_in_process/_in_process.py build_wheel /var/folders/kp/v9675p5n7tqcvd0472jm5b100000gn/T/tmpi2i1dq_5 *cwd*: /Users/jules/Documents/cryptography Building wheel for cryptography (pyproject.toml) ... error ERROR: Failed building wheel for cryptography Failed to build cryptography
