导读：我正在尝试在我的gemfile及其依赖项中安装所有gem,因此只需运行Bundler(bundle或bundle install).在使用本机扩展安装nio4r 1.1.1时失败,下面是登录gem_make.out. /opscode/chef/embedded/bin/ruby.exe -r ./siteconf20150924-7480-ocwr34.rb extconf.rbcheck

Could not create Makefile due to some reason,probably lack of necessary
libraries and/or headers.  Check the mkmf.log file for more details.  You may
need configuration options.

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-make-prog
    --without-make-prog
    --srcdir=.
    --curdir
    --ruby=/opscode/chef/embedded/bin/ruby

You have to install development tools first.

    from extconf.rb:3:in `'

extconf failed,exit code 1

我可以看到捆绑器正在检查unistd.h并且在那时失败了.我确保此标头在PATH中可用,并且还为我的版本安装了ruby devkit.执行gem install nio4r也会出现同样的错误.

解决方法

尝试xcode-select – install first.This可能是xcode构建系统的问题
