Error while gem install rails in Windows 10

Question

Can you explain me what I should do? I've already done adding source of rubygems.org and gem update --system

C:\Ruby22>gem install rails
Temporarily enhancing PATH to include DevKit...
Building native extensions.  This could take a while...

Gem files will remain installed in 
C:/Ruby22/lib/ruby/gems/2.2.0/gems/websocket-driver-0.6.5 for inspection.

I really want to be free from c9. Locaaall!!

This is not issue with rails or rubygems.org . It is related to github. You are using old version of git.

Here is solution for this.

Also you can look into explanation here.

Copied solution from link above:

Both current Cygwin and the new version of MSYS - MSYS2 - already have different logic in place, which is hopefully more robust. It's only old versions of Git for Windows which have been still built using the old broken MSYS system.

Resolution:

Install Git for Windows 2 - it is built with the new, properly maintained MSYS2 and also has many new features, plenty of bug fixes and so on. There is also a 64-bit version available which would lower the chance of address space clashes considerably even if this problem was not fixed. (info) If you're using Embedded Git, you would need to change SourceTree's Git Setting to Use System Git by navigating to Tools>Options>Git(Tab)>Git Version>Use System Git
