Answer 1

Or update npm:

npm install npm -g

Answer 2

An alternative solution that doesn't involve messing with npm installation is to run

SET CL=-DDELAYIMP_INSECURE_WRITABLE_HOOKS %CL%

before running npm install

Answer 3

This error stays in relation with npm, node-gyp and Visual Studio 2015 and is already fixed in node-gyp@3.4.0, but npm is still pointing to an old version. As I workaround I can propose this:

1. Go to your folder where npm is installed, e.g.: C:\Program Files\nodejs\node_modules\npm

2. Open: package.json

3. Remove entry for node-gyp in bundleDependencies

4. Bump version number to 3.4.0 for node-gyp in dependencies

5. Make a npm i in this directory to install node-gyp@3.4.0 to fix the problem
