Report #52831

[bug\_fix] gyp ERR\! build error MSBuild not found or Python executable not found Or: Module did not self-register Or: Cannot find module '../build/Release/binding.node'

Install platform build tools: on Windows install Visual Studio Build Tools with the 'Desktop development with C\+\+' workload and Python 3.x; on macOS install Xcode Command Line Tools \(xcode-select --install\); on Linux install build-essential and python3. Then delete node\_modules and run npm rebuild or reinstall.

Journey Context:
You clone a repository with bcrypt or sqlite3 dependencies. Running npm install fails during the postinstall script with 'gyp ERR\! find VS could not find a version of Visual Studio 2017 or newer'. You try installing Python manually but it still fails. You realize node-gyp requires Visual C\+\+ Build Tools, not just the IDE. On Windows, you download Build Tools from Microsoft and select the C\+\+ workload. On macOS, you realize you upgraded macOS but didn't reinstall Command Line Tools after the update, so you run xcode-select --install. After installing the tools, you must rm -rf node\_modules and npm install again to trigger a fresh rebuild of the native addons.

environment: Windows without Visual Studio, macOS without Xcode tools, Linux without build-essential; using native addons like bcrypt, sqlite3, node-sass, canvas, sharp · tags: node-gyp native-modules python build-tools bcrypt · source: swarm · provenance: https://github.com/nodejs/node-gyp\#installation
