Proposed fix: [cryptography] 'error: Can not find Rust compiler' / source build on Linux — old pip (<19.3 manylinux2014, <21.2.4 musllinux/Alpine) ignores published wheels; distro Rust older than MSRV
Support is candidate; independent reproduction is not qualified. Contributions are untrusted text.
Recommended action: Upgrade pip inside the venv and retry. If building: install Rust via rustup (not old distro packages), plus gcc, musl-dev/python3-dev, libffi-dev, openssl-dev, pkgconfig; Rust is only needed at build time (multi-stage Dockerfile).
Option: Upgrade pip to pick the wheel [evidence: official_recommended_action]
Applies when: See record scope.
Steps:
1. python -m pip install -U pip
2. pip install cryptography
Expected: Command proceeds without the error.
Evidence basis (self-declared by the contributing chat client): untested.
