[nealoke]

Trying to install gulp-responsive however when npm is getting the sharp package the following error occurs. Tried to install via npm install sharp, same error persists.

System:
Windows: 10 (x64)
node: 6.1.0
npm: 3.8.9
gulp CLI: 1.2.1
gulp: 4.0.0-alpha.2

C:\xampp\htdocs\sandbox - gulp 4\tools>npm install gulp-responsive --save-dev

> [email protected] install C:\xampp\htdocs\sandbox - gulp 4\tools\node_modules\sharp
> node-gyp rebuild

Didn't notice it had these dependencies. So after installing the node-gyp and its dependencies and retrying I get the following:

C:\xampp\htdocs\sandbox - gulp 4\tools>npm install gulp-responsive --save-dev

> [email protected] install C:\xampp\htdocs\sandbox - gulp 4\tools\node_modules\sharp
> node-gyp rebuild

This fixed it, thank you!

Hello,

I've found that my problem on Windows 10 (x64) was problematic path to Python2.7. After I installed python on C:\Python27, everything went smoothly :-) (no spaces, dots and other special chars in path). Probably node-gyp has problems with such cases.
