Answer 1

I'm not too familiar with the Habitat setup, but it looks like a common issue with SASS compilation.

It requires an OS/system-dependent binding file, which I believe it first tries to download from Github, but if that fails (e.g. firewalls on company network etc.) it tries to build the needed version - which requires Python 2 to be installed and available on PATH.

You can download Python here (choose the 2.x.x version): https://www.python.org/downloads/

Alternative

You can also download the needed binding file yourself from the releases on Github: https://github.com/sass/node-sass/releases

The logs should tell you which version your system needs. Then copy the file to C:\Users\<username>\AppData\Roaming\npm-cache\node-sass\<version>\. Alternatively you can specify the path to the file with an environment variable SASS_BINARY_NAME.

I got the same error and resolved it by installing/re-installing Node.js. https://nodejs.org/en/download After successful installation 0pen CMD in Administrator mode and Go to your project directory to run npm install command. Make sure the Path/npm install should be where the gulp-config.js file exist.
