嘿，我是Rails(以及Linux)的新手，但我不断收到此错误:
Installing json (1.7.5) with native extensions
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.
/usr/bin/ruby1.9.1 extconf.rb
/usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file -- mkmf (LoadError)
from /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require'
from extconf.rb:1:in `<main>'
Gem files will remain installed in /home/jack/.bundler/tmp/10426/gems/json-1.7.5 for inspection.
Results logged to /home/jack/.bundler/tmp/10426/gems/json-1.7.5/ext/json/ext/generator/gem_make.out
An error occurred while installing json (1.7.5), and Bundler cannot continue.
Make sure that `gem install json -v '1.7.5'` succeeds before bundling.

我无法单独或通过捆绑安装来安装gem。我使用rvm安装滑轨。提前致谢。
最佳答案
安装ruby1.9.1-dev软件包应该为您解决此问题
sudo apt-get install ruby1.9.1-dev
