ruby-on-rails - 安装 FeedZirra 时出错

Question

我是 Ruby on Rails 的新手。我对 Feed 解析感到很兴奋，但是当我安装 FeedZirra 时，我收到了这个错误。

我使用 Windows 7 和 Ruby 1.8.7。

请帮忙。提前致谢。

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:

  Try passing --with-curl-dir or --with-curl-lib and --with-curl-include
  options to extconf.

我尝试从 x1a4 提到的链接下载 curl。它不适用于 ruby​​ 1.9.2，即使安装了开发工具包也是如此:

C:\>gem install feedzirra -- --with-curl-lib=c:\curl-7.21.3-devel-mingw32\lib --with-curl-include=C:\curl-7.21.3-devel-mingw32\include
