See the other issues about __pfnDliNotifyHook2. To summarize, upgrade to node-gyp v3.4.0.

[emum8]

I am using v3.4.0 I think

[bnoordhuis]

From the log you posted:

gyp ERR! node-gyp -v v3.3.1

[emum8]

Hmm could that be the version that comes with the npm package I am trying to install?
node-gyp -v says v3.4.0

[bnoordhuis]

Quite possible. Try upgrading to npm@latest.

[emum8]

I uninstalled nodejs and deleted the modules/other node/npm folders and reinstalled then updated npm.
It's working now, ty.

[laggingreflex]

I was getting the same error. Upgraded from node-v6.6.0 to node-v6.8.1 and it worked.

Bug related to node-gyp is also mentioned been fixed on npm v3.10.5 release page

[360disrupt]

I cannot install it. Node v.6.9, node-gyp 3.4 & npm v3.10.8.

@360disrupt That error probably means node-gyp couldn't find a working python binary. --verbose should tell you where it's looking. You can override it with --python /path/to/python.

[360disrupt]

python -V gives me Python 2.7.11
But what helped was: npm config set python python2.7

[bnoordhuis]

Good, that's basically the persistent version of --python.

@kenken64 I think you need to set f:\ProgramData\Anaconda3\python.EXE as python path in the environment variable
