[bug\_fix] Source distribution build failure due to missing system compilers \(gcc/clang\) or Python headers

Install system build dependencies: on Debian/Ubuntu 'apt-get install python3-dev gcc', on RHEL/CentOS 'yum install python3-devel gcc', on macOS 'xcode-select --install', or use '--only-binary :all:' to force pre-built wheels. Root cause: When a package lacks a manylinux wheel for the specific platform \(e.g., Alpine Linux musl, or ARM64\), pip falls back to building from source \(sdist\). Compiling C extensions requires a C compiler and Python development headers which are not present in minimal images \(slim, alpine\) or fresh systems.

Journey Context:
You run 'pip install psutil' in a 'python:3.11-slim' Docker container. Pip downloads psutil-5.9.5.tar.gz and prints 'Building wheel for psutil \(pyproject.toml\): started'. After several seconds, it fails with 'error: command 'gcc' failed: No such file or directory'. You realize the slim image lacks build tools. You try 'apt-get update && apt-get install -y gcc python3-dev' and retry, and the build succeeds. Later, you optimize the Dockerfile to use 'pip install --only-binary :all: psutil' which forces pip to only use wheels, failing fast if no wheel exists rather than trying to compile. For Alpine Linux \(musl\), you switch to manylinux-compatible images or install 'musl-dev gcc' since manylinux wheels don't work on Alpine.

environment: Docker slim/alpine images, minimal CI runners \(GitHub Actions ubuntu-latest without build-essentials\), fresh macOS without Xcode tools, Windows without Visual C\+\+ Build Tools. · tags: pip wheel sdist build-failure gcc docker slim manylinux musl · source: swarm · provenance: https://pip.pypa.io/en/stable/cli/pip\_install/\#install-binary and https://packaging.python.org/en/latest/tutorials/installing-packages/\#source-distributions-vs-wheels
