I am trying to install a web3js dependency for my project. But there is an issue coming up with node-gyp.
Below is the error log for that"

install windows-build-tools before installing web3 and its dependencies
npm install --global --production windows-build-tools
reference: https://github.com/nodejs/node-gyp
I had to install the above windows-build-tools but had to install with npm install --global --production windows-build-tools --vs2015 as the newer versions of this tool are going to not compile the web3 utils correctly with the node-gyp dependency. I wrangled this one for a while after uninstalling an old install of Visual Studio 2015 a couple of weeks ago.

the easiest way to install sharp on windows OS is to use the following npm package
which is called windows-build-tools
npm install --global --production windows-build-tools
this as npm says it downloads
installs Visual C++ Build Tools, provided free of charge by Microsoft. These tools are required to compile popular native modules. It will also install Python 2.7, configuring your machine and npm appropriately.
after this npm install sharp
I am currently working on a fresh minimal install of Ubuntu 16.0.4 using Hyperledger Fabric. I have pulled down a fresh install of the fabric samples from the Hyperledger documentation site. I have downloaded the following software:
node version 6.9.5
npm version 3.10.10
docker version 17.03.2-ce
golang version 1.7.6 (documentation now calls for newer version, but I think this is unrelated)
I can navigate to the fabcar directory which contains the default npm package.json. I first run ./startFabric as indicated in the instructions. I then run npm install, per the instructions. I then get the error:
u#ubmin2:~/fabric-samples/fabcar$ npm install
npm WARN deprecated crypto#0.0.3: This package is no longer supported. It's now a built-in Node module. If you've depended on crypto, you should switch to the one that's built-in.

Thank you.
The issue was that I was missing a necessary c++ compiler. It seems it was not included in the Ubuntu minimal installation, which makes sense, but the errors seemed very opaque. Running sudo apt install build-essential g++ seems to have solved the problem.
I'm not sure if it was necessary, but I also needed to add alias sudo='sudo env PATH=$PATH' to my .bashrc file so I could run npm with sudo. That solution came from this link.
