gem install kgio ERROR

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: ERROR: Failed to build gem native extension.C:/Ruby193/bin/ruby.exe extconf.rb checking for CLOCK_MONOTONIC in time.h... no checking for CLOCK_MONOTONIC() in time.h... no checking for clockid_t in time.h... no checking for clock_gettime() in -lrt... no checking for t_open() in -lnsl... no checking for socket() in -lsocket... no checking for poll() in poll.h... no checking for getaddrinfo() in sys/types.h,sys/socket.h,netdb.h... no getaddrinfo required *** extconf.rb failed *** Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers.

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

我确实输入了: bundle install之后,但什么都没发生..

kgio仅适用于* nix系统。

kgiogem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exception。 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。

试试这个

 platforms :ruby do # linux gem 'unicorn' end platforms :mswin do # gems specific to windows end

我认为你正在使用Windows操作系统,所以你只需要知道这个错误就是在你的gem文件中注释或删除gem’unicorn’ ,因为这只适用于linux系统
