Installing node-ffi on Windows

Question

I'm trying to install node-ffi on my Windows development machine, but the install fails. According to the node-ffi webpage, Windows should be supported. However, it appears that gyp is trying to execute something through "sh", which (obviously) is not present on my system. Any ideas?

D:\code\ffi-test>npm install node-ffi
npm http GET https://registry.npmjs.org/node-ffi
npm http 304 https://registry.npmjs.org/node-ffi
npm http GET https://registry.npmjs.org/bindings
npm http 304 https://registry.npmjs.org/bindings

> node-gyp rebuild

Answer 1

in cmd set Visual Studio path depending upon ur version as

Visual Studio 2010 (VS10): SET VS90COMNTOOLS=%VS100COMNTOOLS%

Visual Studio 2012 (VS11): SET VS90COMNTOOLS=%VS110COMNTOOLS%

Visual Studio 2013 (VS12): SET VS90COMNTOOLS=%VS120COMNTOOLS%

Check if python is installed and configured .

Python version <3 is required

then in cmd use command

npm install ffi

to install ffi . For more help look at Cannot install node modules that require compilation on Windows 7 x64/VS2012

npm install ffi

Watch the documentation: https://github.com/rbranson/node-ffi

For visual studio 2017 try this in powershell to set environment variable
