我尝试根据http://lenni.info/blog/2012/05/installing-ruby-1-9-3-on-ubuntu-12-041.8将我的 ruby​​ 版本从（默认）切换到1.9.3（Pangolin 的最新版本） -精确的企鹅/。我正在使用apt.

SO相关问题的其他解决方案涉及apt-get install ruby1.9.3-dev但我肯定有。

$ sudo gem install idn
Building native extensions.  This could take a while...
ERROR:  Error installing idn:
        ERROR: Failed to build gem native extension.

idna.c: In function ‘toUnicode’:
idna.c:128:41: error: ‘struct RString’ has no member named ‘ptr’
make: *** [idna.o] Error 1


Gem files will remain installed in /var/lib/gems/1.9.1/gems/idn-0.0.2 for inspection.
Results logged to /var/lib/gems/1.9.1/gems/idn-0.0.2/ext/gem_make.out

我还检查了我是否已gcc安装，并且再次从apt.

$ ruby -v
ruby 1.9.3p0 (2011-10-30 revision 33570) [x86_64-linux]

我可能会放弃这个。我能够安装punycode4rgem，这适用于我正在尝试做的事情。
