我正在尝试在 ruby​​ 1.9.3 上安装 iconv (gem)，但是运行时失败：

宝石安装图标v

Building native extensions.  This could take a while...
ERROR:  Error installing iconv:
    ERROR: Failed to build gem native extension.

Gem files will remain installed in /home/adhown/.rbenv/versions/1.9.3-p0/lib/ruby/gems/1.9.1/gems/iconv-0.1 for inspection.
Results logged to /home/adhown/.rbenv/versions/1.9.3-p0/lib/ruby/gems/1.9.1/gems/iconv-0.1/ext/iconv/gem_make.out

我用 rbenv 安装 ruby​​ 是否相关？

谁知道怎么解决，谢谢。

删除 iconv gem 并使用 String#encode 代替。

这将返回 my_string_variable utf-8 编码的字符串副本：

my_string_variable.encode('utf-8', {:invalid => :replace, :undef => :replace, :replace => ''})

参见：Ruby-Doc
