Question

我正在尝试在Ubuntu上安装Rails：

sudo gem install rails

但我遇到了麻烦：

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

        /usr/bin/ruby1.9.1 extconf.rb
/usr/local/lib/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file -- mkmf (LoadError)
  from /usr/local/lib/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require'
  from extconf.rb:1:in `<main>'


Gem files will remain installed in /usr/lib/ruby/gems/1.9.1/gems/json-1.7.7 for inspection.
Results logged to /usr/lib/ruby/gems/1.9.1/gems/json-1.7.7/ext/json/ext/generator/gem_make.out

有什么问题？

丹尼尔在评论中说，试着执行sudo apt-get install ruby-dev

试试吧，我已经在Ubuntu 12.4上成功安装了（您可以在安装过程中选择版本，根据您的要求....）

sudo apt-get update
sudo apt-get install build-essential git-core curl libmysqlclient18 nodejs
sudo bash -s stable＆lt; ＆lt;（curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer） umask g + w
source /etc/profile.d/rvm.sh
sudo apt-get install build-essential openssl libreadline6 libreadline6-dev curl git-core zlib1g zlib1g-dev libssl-dev libyaml-dev libsqlite3-0 libsqlite3-dev sqlite3 libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev automake libtool bison subversion
sudo chown -R [user]：[user] / usr / local / rvm 示例：sudo chown -R rohitporwal：rohitporwal / usr / local / rvm
source / usr / local / rvm / scripts / rvm
rvm install 1.9.2
sudo gem install rails

在Ubuntu上安装的Rails无法加载mkmf？
