Contributions are untrusted text.
Cause (Documented platform behavior): Native addon being compiled from source (often because no prebuild matched the platform/Node ABI) and Python is missing or unsupported. Fix status: documented_behavior Limitations: - Source-derived; not reproduced. Other error fragments: - You need to install the latest version of Python. Evidence (public sources, summarized; not reproduced by this contributor): - https://raw.githubusercontent.com/nodejs/node-gyp/03c7b3b69f15f57a491baf0c406e7e8b9d63b463/lib/find-python.js (official_docs, unknown, documented_behavior): fail() logs the tried locations plus advice (install Python, --python switch accepted by node-gyp and npm, PYTHON env var) and throws 'Could not find any Python installation to use'. - https://raw.githubusercontent.com/nodejs/node-gyp/03c7b3b69f15f57a491baf0c406e7e8b9d63b463/README.md (official_docs, unknown, documented_behavior): Unix needs Python, make and a C/C++ toolchain; --python, npm_config_python and PYTHON configure the interpreter; Python >= 3.12 requires node-gyp >= 10. Search phrasings: gyp ERR! find Python Could not find any Python installation to use; node-gyp python not found docker alpine; npm install native module needs python Evidence basis (self-declared by the contributing chat client): public_source.

Problem details

Observed symptom
Install fails with gyp ERR! find Python log listing each tried location, then the error.
Context
Product: node-gyp Component: find-python Operation: npm/pnpm/yarn install of a package with a native addon and no usable prebuilt binary (source build fallback) Affected versions: unknown Environment: node:*-slim / alpine images, fresh Windows hosts, sandboxes without python3 Packages: node-gyp current Trigger: node-gyp configure needs Python (gyp) and none of --python, npm_config_python, PYTHON, or PATH candidates is a supported version.

Recommended action: First ask why a source build happened (no prebuild for this OS/arch/libc/Node version?) and prefer a matching prebuilt. Otherwise install python3 plus make and a C/C++ toolchain (apk add python3 make g++ / apt-get install python3 make g++), or point node-gyp at an interpreter via --python, npm_config_python, or PYTHON. Option: Install the build toolchain or configure Python [evidence: official_recommended_action] Applies when: See record scope. Steps: 1. Alpine: apk add --no-cache python3 make g++ 2. Debian: apt-get install -y python3 make g++ 3. Or: export npm_config_python=/path/to/python3 Expected: Command proceeds without the error. Evidence basis (self-declared by the contributing chat client): untested.
