Question

我是ruby和rails的新手。我已成功在rails 4上设置ruby 2（在Windows 7上）。我在基于git项目的rails上克隆了一个ruby（thingspeak - https://github.com/iobridge/thingspeak/blob/master/README.textile）。使用命令行，我进入项目目录并运行＆＃34; bundle install＆＃34;。下载并安装了一些软件包然后我收到了以下错误 -

::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension
.

    c:/row/Ruby200/bin/ruby.exe extconf.rb

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=.

        --with-nsllib
        --without-nsllib

        --without-socketlib

Gem files will remain installed in c:/row/Ruby200/lib/ruby/gems/2.0.0/gems/kgio-
2.8.1 for inspection.

m_make.out
An error occurred while installing kgio (2.8.1), and Bundler cannot continue.
Make sure that `gem install kgio -v '2.8.1'` succeeds before bundling.

关于它意味着什么以及如何解决它的任何想法？

Answer 1

此处无法编译的kgio gem在Windows上不起作用。如果您对Gemfile中的相应行进行评论，但可以工作，但在其他各个地方可能会失败。

通常，您要安装的Rails应用程序似乎根本不在Windows上进行测试，因此您可能希望使用更好的支持操作系统来安装它。 README在这里提到了Ubuntu。
