I have installed node js latest version(8.8.1) and npm latest version(5.5.1) and when i try to install node-sass i get this:

npm install -g node-sass 

C:\Users\Giannis\AppData\Roaming\npm\node-sass -> C:\Users\Giannis\AppData\Roaming\npm\node_modules\node-sass\bin\node-sass

[email protected] install C:\Users\Giannis\AppData\Roaming\npm\node_modules\node-sass node scripts/install.js

'node' is not recognized as an internal or external command, operable program or batch file. npm ERR! code ELIFECYCLE npm ERR! errno 1 npm ERR! [email protected] install: node scripts/install.js npm ERR! Exit status 1 npm ERR! npm ERR! Failed at the [email protected] install script. npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

npm ERR! A complete log of this run can be found in: npm ERR! C:\Users\Giannis\AppData\Roaming\npm-cache_logs\2017-10-26T11_57_10_751Z-debug.log

I have set the system variable C:\Program Files\nodejs\

Thanks

Answer 1

node-sass requires node-gyp https://github.com/sass/node-sass#install

node-gyp requires windows-build-tools https://github.com/nodejs/node-gyp#on-windows

Install all the required tools and configurations using Microsoft's windows-build-tools using npm install --global --production windows-build-tools from an elevated PowerShell or CMD.exe (run as Administrator).

Answer 2

Using the npm install --global --production windows-build-tools on an Elevated prompt works for me. The installer got stuck on visual studio build tools, but they were already installed on my system. So i ctrl +c the npm install process and run it once again. This time a messages shows up that the build tools are already installed and the installation will be skipped and continued with python configuration.

Finally the node-sass installation completed successfully.

BTW node-sass usage is deprecated and will be removed. The suggestion is to start using sass.
