npm install fails with node-gyp build error

Question

Today when I run npm install , it fails and gives me the following error log. I know it's an issue with hashtable but I have never had this issue before.

I thought there might be a problem with node-gyp so I did a npm install node-gyp -g separately but the issue did not go away. Does anyone know how to resolve this?

By the way, I am on Mac,running OSX 10.11.5, also recently installed XCode 6.3.2 for a separate project and can only use this version of XCode, not sure if that is causing the problem.

node-gyp also requires python and xcode on MacOs for C++ compilation. There are similar requirements for other systems.

You can find the pre-reqs for the node-gyp package on its npm page here .
