在Ubuntu 11上安装Rails时出现此问题：

root@salah:/home/salah/rubygems-1.8.15# sudo gem install mysql

Fetching: mysql-2.8.1.gem (100%)
Building native extensions.  This could take a while...
ERROR:  Error installing mysql:

Gem files will remain installed in /usr/lib/ruby/gems/1.9.1/gems/mysql-2.8.1 for inspection.

Answer 1

如果我没弄错的话，mkmf是ruby-dev软件包的一部分。尝试：

sudo aptitude install ruby1.9.1-dev

当然，最好通过RVM安装ruby：）

Answer 2

对于ubuntu 13.04，这对我有用：

sudo apt-get install ruby-dev

Answer 3

试 rvm all do gem install nokogiri

Ubuntu上的Rails安装失败，“无法加载此类文件 - mkmf”
