node-sass build failed

Published Aug 9, 2018

Common issue while developing angular at Windows machine is node-sass build error.

Example error output:

gyp ERR! build error
gyp ERR! stack Error: `msbuild` failed with exit code: 1
gyp ERR! stack     at ChildProcess.onExit ([....]\node_modules\node-gyp\lib\build.js:258:23)

gyp ERR! cwd [....]node_modules\node-sass
gyp ERR! node -v v10.0.0
gyp ERR! node-gyp -v v3.6.2
gyp ERR! not ok
Build failed with error code: 1

Solution for this is installing build tools.

Open Poershell with Administrator privilages
Run following command:

npm install -g windows-build-tools

Unfortunately this must be called after VisualStudio Update :(
