Report #14211

[bug\_fix] gyp ERR\! find Python or gyp ERR\! find VS

Root cause: 'node-gyp' \(the native addon build tool used by npm/yarn/pnpm to compile C\+\+ addons\) requires Python 3.x and a C\+\+ compiler toolchain. On Windows, this means Visual Studio Build Tools \(specifically the 'Desktop development with C\+\+' workload\) and Python 3. On macOS, it requires Xcode Command Line Tools. On Linux, 'build-essential' and 'python3'. If these are missing or not in PATH, compilation of native modules \(like 'bcrypt', 'sharp', 'sqlite3'\) fails. Fix: Install the required tools. On Windows: Install 'Visual Studio Build Tools' with the 'Desktop development with C\+\+' workload, and Python 3 from python.org, ensuring 'python3' is in PATH. Then configure npm: 'npm config set python python3' and 'npm config set msvs\_version 2022'. On macOS: 'xcode-select --install'. On Linux: 'sudo apt-get install build-essential python3 make'.

Journey Context:
A developer clones a repo using 'bcrypt' for password hashing on a fresh Windows 11 machine. They run 'npm install'. The install proceeds until it reaches 'bcrypt', then fails with 'gyp ERR\! stack Error: Can't find Python executable "python", you can set the PYTHON env variable.' The developer installs Python 3.11 from python.org and restarts the terminal. They run 'npm install' again. Now it fails with 'gyp ERR\! find VS could not find Visual Studio installation'. The developer realizes they need the C\+\+ compiler. They download 'Visual Studio Build Tools 2022' and install the 'Desktop development with C\+\+' workload \(about 6GB\). They run 'npm config set msvs\_version 2022' and 'npm config set python python3'. Finally, they delete 'node\_modules' and run 'npm install' again. The 'bcrypt' package now compiles successfully against the Node.js headers using the newly installed compiler and Python.

environment: Fresh development machines \(Windows, macOS, or Linux\) without pre-installed build tools, especially when installing packages with native dependencies like 'bcrypt', 'sharp', 'node-sass', 'sqlite3'. · tags: node-gyp python visual-studio build-tools native-addon windows-build-tools bcrypt · source: swarm · provenance: https://github.com/nodejs/node-gyp\#installation
