NPM install fails with node-gyp

Question

We are having problems running "npm install" on our project. A certain file cannot be found :

fatal error C1083: Cannot open include file: 'windows.h' 

It appears to be coming from the node-gyp module :

c:\Program Files\nodejs\node_modules\npm\node_modules\node-gyp\src\win_delay_lo ad_hook.c(13):

fatal error C1083: Cannot open include file: 'windows.h': No suc h file or directory [D:\ngs-frontend-next\node_modules\browser-sync\node_module s\socket.io\node_modules\engine.io\node_modules\ws\node_modules\bufferutil\buil d\binding.sln]

This node-gyp seems to be a never ending source of pain for us. At first it complained that it needed python, so we installed that. Then it complained that it needed VCBuild, which we installed (using .NET 2.0 SDK), now we have this error. It's almost as if the errors are getting more and more obscure, and it feels like we are going down some wrong path.

The strange thing is, that other people in our team have zero problems running the npm-install.

The full error looks like this :

c:\Program Files\nodejs\node_modules\npm\node_modules\node-gyp\src\win_delay_lo ad_hook.c(13):

Answer 1

The error messages have caused confusion for me and have not helped me in resolving the errors completely.

The README.md for node-gyp project does a better job of listing down the installation instructions for Unix, Max OS X and Windows.

In Windows systems you can either go with Option 1 or Option 2 but the main thing is that you need to install the Visual C++ Build Tools.

The following quote is from the Windows installation section:

• On Windows:
  • Visual C++ Build Environment:
    • Option 1: Install Visual C++ Build Tools using the Default Install option.
    • Option 2: Install Visual Studio 2015 (or modify an existing installation) and select Common Tools for Visual C++ during setup. This also works with the free Community and Express for Desktop editions.
    
    [Windows Vista / 7 only] requires .NET Framework 4.5.1
  • Install Python 2.7 (v3.x.x is not supported), and run

    npm config set python python2.7

    (or see below for further instructions on specifying the proper Python version and path.)
  • Launch cmd,

    npm config set msvs_version 2015

If the above steps didn't work for you, please visit Microsoft's Node.js Guidelines for Windows for additional tips.

Common instructions for Python configuration:

If you have multiple Python versions installed, you can identify which Python version node-gyp uses by setting the '--python' variable:

$ node-gyp --python /path/to/python2.7

If node-gyp is called by way of npm and you have multiple versions of Python installed, then you can set npm's 'python' config key to the appropriate value:

$ npm config set python /path/to/executable/python2.7

Successfully configured my system following the above instructions.
