[bug\_fix] gyp ERR\! stack Error: Python not found

Set the PYTHON environment variable to the path of Python executable, or install Python \(2.7 or 3.x\) and add it to PATH, then rebuild.

Journey Context:
On a Linux CI runner, a native npm package \(sharp\) failed to build with 'Python not found'. The node-gyp build step requires Python to run gyp files. The runner had Python installed but it was at \`/usr/bin/python3\`, not \`python\`. I fixed by exporting \`PYTHON=/usr/bin/python3\` before \`npm install\`. Alternatively, I could have symlinked \`python\` to \`python3\`. The root cause is that node-gyp looks for \`python\` in PATH by default; if it's missing or named differently, the build fails. The fix ensures node-gyp finds the Python interpreter.

environment: Ubuntu 22.04, Node 16.20.0, npm 8.19.3, building sharp in Docker · tags: node-gyp python-not-found gyp-err · source: swarm · provenance: node-gyp README: https://github.com/nodejs/node-gyp\#installation \(section on Unix/macOS\)
