support windows

[bbatsov]

I guess this just re-emerged in the context of RuboCop - see https://github.com/rubocop-hq/rubocop/issues/5989

Perhaps on Windows you can just fallback automatically to the pure Ruby version?

[tonytonyjan]

The issue seems similar to this: https://stackoverflow.com/questions/19176136/make-is-not-recognized-as-internal-or-external-command

In theory, it should have worked on Windows since the extension is implemented with CRuby's interface, but I never had tested jaro_winkler on windows before.

I'll confirm this issue on windows 10 later.

[tonytonyjan]

Oops, I suddenly realized I misread rubocop-hq/rubocop#5989, it's JRuby on windows platform.

[rtdevlin]

I'm still seeing this issue on 64 bit Ruby2.3.1 on Windows. Popped up with recent Rubocop update

@rtdevlin Would you paste the full error message here, thank you!

@rtdevlin I am not able to reproduce your issue:

I guess It might have something to do with your building environment. Are you able to install other C extensions? For example: gem install thin

[rtdevlin]

I wasn't able to install thin, but I know I've installed gems that required the Devkit and it worked. The only difference I see right now is Windows versions. I'm going to try to install on my home machine (the issue I'm having is at work, else I wouldn't be using Windows)

[rtdevlin]

Was able to install on Windows 10. Thanks for looking into the issue, I'll continue trying to figure out what's wrong with my machine

Still running into issues on this. Windows 10 x64:

I was able to fix this by uninstalling ruby (installed via Chocolatey) and manually installing RubyInstaller+DevKit https://rubyinstaller.org/downloads/

[Dainii]

If it can help someone, I had the same issue and the problem was the path of my ruby installation. It was installed in "C:\Program Files\ruby" and Make does not seems to like the space in the path of the executables.

So I moved the folder elsewhere (like "C:\DATA") and it works now.

For folks who use scoop on Windows

$ scoop install ruby
$ scoop install msys2
$ ridk install
# PRESS ENTER (installs MSYS2 + MINGW Development Kit)  

This should make gem install jaro_winkler work just fine

[Slach]

@okmanideep thanks for sharing. it works
