ruby-on-rails - 无法在 Windows PC 上安装 dm-sqlite-adapter Gem

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。我之前确实使用命令 gem install sqlite3 安装了 sqlite3。但是，如果我尝试调用 gem install sqlite3 --platform=ruby，则会出现错误。

  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

        --srcdir=.
        --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 开发工具包，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该工具要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方法来让它工作，我意识到这可能是一个愚蠢的问题。但是，在这一点上，我没有主意。非常感谢任何帮助。

我最终能够解决这个问题。对于那些在未来遇到这个问题的人，Bosko Ivanisevic 写了一篇很好的指南来解决这个问题。

参见此处:http://rubyonwindowsguides.github.io/book/ch02-05.html

里面有很多细节需要注意，所以一定要一步一步地通读，并严格按照每一项进行操作。很好的解释。
