Report #29054

[bug\_fix] gyp ERR\! build error \| Can't find Python executable 'python', you can set the PYTHON env variable \| MSBuild not found

Install platform-specific C\+\+ build tools: on Windows install Visual Studio Build Tools with 'Desktop development with C\+\+' workload \(or windows-build-tools npm package on older systems\), on macOS install Xcode Command Line Tools \(xcode-select --install\), on Linux install build-essential and python3.

Journey Context:
Developer clones a repository and runs npm install on a Windows machine without Visual Studio. The install fails when reaching a package with native bindings \(e.g., bcrypt, sqlite3, sharp\) with 'gyp ERR\! stack Error: Can't find Python executable python'. The developer installs Python from python.org, but the error changes to MSBuild or 'Visual Studio not found'. Realizing that node-gyp requires a C\+\+ compiler toolchain to compile native addons against Node.js headers, the developer installs Visual Studio Build Tools 2019 with the C\+\+ workload. On macOS, the fix requires accepting the Xcode license and installing CLI tools. The fix works because node-gyp is a cross-platform build tool that generates platform-specific project files \(Makefile/MSBuild\) to compile C\+\+ source files into .node binaries linked against the V8 engine, and it requires Python for its build scripts and a native compiler toolchain.
