node-microtime: Error running npm install

FYI to everyone that had issues here. The latest release (2.1.4) of microtime now uses node-pre-gyp to provide pre-built binaries for Windows users.

I think the issue that affected everyone here is https://github.com/crypto-browserify/pbkdf2/commit/ad53c33ff1bb51ee9d7586a974feab9b3925854e. That bump essentially screwed over everyone using browserify.

I can verify that running the following in an elevated CMD works on Windows (after installing Python 2.7 and setting %PYTHON%):

npm install --global --production windows-build-tools
npm install -g npm

@ukphillips your computer is not set up to compile and build any native C++ modules (like microtime). You didn’t notice before because nothing in your project used native modules, but when pbkdf2 added microtime as a dependency you encountered your first native module. So the answer is, your computer could never install microtime, you just didn’t notice before. If you want to install native modules, you need to follow these steps: https://github.com/nodejs/node-gyp#installation

I just re-ran the automated builds and microtime builds on windows for all current versions of Node.js: https://ci.appveyor.com/project/WadeSimmons/node-microtime/build/88

Here is my challenge… this is for a web application. Why python would be needed for whatever javascript library is using is it concerning.

Ignoring that, I just tried to install that specific version of node-gyp (which is a dependency for who knows what library I’m importing) and get this:

$ npm install node-gyp@3.6.1

microtime@2.1.3 install C:\Development\node_modules\microtime node-gyp rebuild

Your first error says:

gyp ERR! stack Error: Can't find Python executable "python", you can set the PYTHON env variable.

So check that you have python installed and set up correctly.

The second error says:

File "C:\Users\me\AppData\Roaming\npm\node_modules\npm\node_modules\node-gyp\gyp\pylib\gyp\MSVSVersion.py", line 434, in SelectVisualStudioVersion
versions = _DetectVisualStudioVersions(version_map[version], 'e' in version)
KeyError: '2017'

I’m guessing you are using VS2017? It looks like support for that version was added in node-gyp 3.6.0, so try upgrading your node-gyp.
