The latest cairo gem drops windows support on ruby 1.9.3

[shuaimu]

which will make green shoes throw " cannot load such file -- cairo.so (LoadError)" error.

[viveikt]

Same problem here. Can anyone please help

[shuaimu]

just upgrade to 2.1 should temporarily fix this problem

@msmummy : I uninstalled ruby 1.9.3 and installed ruby 2.1 from the ruby installer in windows. After that I could not find the green shoes gem in the gem list.

So when I tried to install it back. I got this. Can you help?
