我今天晚上遇到了这个问题(Windows 7，Ruby 1.9.3)。我的解决方案如下:

1. 安装来自 http://gnuwin32.sourceforge.net/packages/libiconv.htm 的“完整包，源代码除外”

2. 运行 gem install iconv -v '1.0.4' -- --with-iconv-dir=/path/to/GnuWin32

如果这不起作用，我也首先按照此处的说明进行操作:http://donpepeto.com/2014/09/20/fixing-c-libraries-on-your-rubyrails-install-on-windows/ (从 GnuWin32 安装中复制/bin、/include 和/lib 的内容)它们不能单独工作，但是一旦我运行安装程序，我就能够安装 gem，所以这可能有所帮助。我还收到有关缺少 .gitignore 的错误，但我忽略了它，再次运行 gem install... 并且成功了。
