宝石安装kgio错误 [英] gem install kgio ERROR

问题描述

我已经下载了一个rails开源web应用程序，并且正在使用它：

I've downloaded a rails open source webapp , and while i was starting it using :

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

我试图用下面的方法修正这个错误：

i tried to fix this error using:

cmd:>gem install kgio -v '2.8.0'

出现错误：

i got the error:

推荐答案

kgio仅适用于* nix系统。

kgio is only for *nix system.

kgio宝石页面：

the kgio gem page:

kgio 2.8.0 kgio为Ruby提供了非阻塞I / O方法，没有
引发EAGAIN和EINPROGRESS的异常。它打算与独角兽和彩虹一起使用
！机架式服务器，但可能被其他
应用程序（运行于类Unix平台上）使用。

kgio 2.8.0 kgio provides non-blocking I/O methods for Ruby without raising exceptions on EAGAIN and EINPROGRESS. It is intended for use with the Unicorn and Rainbows! Rack servers, but may be used by other applications (that run on Unix-like platforms).
