ruby - 无法安装某些 gem

Question

我尝试在 Linux 下安装一些 gem ( roo )。

# uname -a Ubuntu-1304-raring-64-minimal 3.8.0-19-generic#30-Ubuntu SMP 5 月 1 日星期三 16:35:23 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

但响应错误:

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

  /usr/local/rvm/rubies/ruby-2.0.0-p195/bin/ruby extconf.rb

Gem files will remain installed in /usr/local/rvm/gems/ruby-2.0.0-p195/gems/nokogiri-1.6.0 for inspection.
Results logged to /usr/local/rvm/gems/ruby-2.0.0-p195/gems/nokogiri-1.6.0/ext/nokogiri/gem_make.out

为什么？

Answer 1

您使用系统 Ruby，需要 ruby-dev 包来安装 native 扩展。我建议切换到任何版本管理器，例如 RVM 或 rbenv。之后此错误应该会消失。
