Question

我是Ruby / Sinatra的新手，我正在尝试安装DataMapper SQLite适配器。当我运行gem install dm-sqlite-adapter时，我收到以下消息。我之前使用命令gem install sqlite3安装了sqlite3。但是，如果我尝试拨打gem install sqlite3 --platform=ruby，我会收到错误。

  c:\Ruby_Dev_Kit>gem install dm-sqlite-adapter
Temporarily enhancing PATH to include DevKit...
Building native extensions.  This could take a while...
ERROR:  Error installing dm-sqlite-adapter:
        ERROR: Failed to build gem native extension.

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

        --curdir

        --with-sqlite3-dir
        --without-sqlite3-dir

        --without-sqlite3-include=${sqlite3-dir}/include
        --with-sqlite3-lib
        --without-sqlite3-lib=${sqlite3-dir}/


Gem files will remain installed in C:/Ruby200-x64/lib/ruby/gems/2.0.0/gems/do_sq
lite3-0.10.13 for inspection.

我尝试了多种不同的方法来解决这个问题。我能够安装Ruby Development Kit，因为我能够安装JSON gem。同样，我从SQLite.org下载了SQLite源代码，但我无法弄清楚如何正确配置工具找到的合并的所有方面。以下是mkmf.log的值：

我尝试了许多不同的东西来使它工作，我意识到这可能是一个愚蠢的问题。但是，在这一点上，我没有想法。任何帮助都会非常感激。

我最终能够解决这个问题。对于那些在未来遇到这种情况的人来说，Bosko Ivanisevic写了一篇很好的指南，告诉他们如何解决这个问题。

见这里：http://rubyonwindowsguides.github.io/book/ch02-05.html

在那里要注意许多细节，所以一定要逐步阅读并完全遵循一切。很好的解释。
