ruby - 在 ruby​​ 1.9.3 上安装 iconv 失败

Question

我正在尝试在 ruby​​ 1.9.3 上安装 iconv (gem)，但是当我运行时它失败了:

gem install iconv

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

        /home/adhown/.rbenv/versions/1.9.3-p0/bin/ruby extconf.rb

make
compiling iconv.c

compilation terminated.
make: *** [iconv.o] Error 1


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

和我用rbenv安装ruby有关系吗？

谁知道怎么解决，谢谢。

移除 iconv gem 并改用 String#encode。

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 => ''})
