gem install kgio ERROR

Question

我已经下载了一个rails开源webapp,当我开始使用时:

C:\Users\admin\Downloads\iCare\icare-develop>rails server
?[31mCould not find kgio-2.8.0 in any of the sources?[0m
?[33mRun `bundle install` to install missing gems.?[0m

我尝试使用以下方法修复此错误:

cmd:>gem install kgio -v '2.8.0'

我收到了错误:

Temporarily enhancing PATH to include DevKit...
Building native extensions.  This could take a while...
ERROR:  Error installing kgio:

Provided configuration options:
        --with-opt-dir
        --without-opt-dir
        --with-opt-include
        --without-opt-include=${opt-dir}/include
        --with-opt-lib
        --without-opt-lib=${opt-dir}/lib

        --with-nsllib
        --without-nsllib
        --with-socketlib
        --without-socketlib

和Gem文件将保持安装在C:/Ruby193/lib/ruby/gems/1.9.1/gems/kgio-2.8中.0用于检查.结果记录到C:/Ruby193/lib/ruby/gems/1.9.1/gems/kgio-2.8.0/ext/kgio/gem_ma ke.out

我输入了:bundle install之后,但什么也没发生..

kgio仅适用于*nix系统.

kgio宝石页面:

kgio 2.8.0 kgio为Ruby提供非阻塞I/O方法,而不会在EAGAIN和EINPROGRESS上引发异常.它适用于Unicorn和Rainbows!机架式服务器,但可能被其他应用程序(在类Unix平台上运行)使用.
