ruby 1.9.3p484 (2013-11-22 revision 43786) [x86_64-linux]
Rails 4.0.0
Bundler version 1.7.9
当我转到我的项目文件夹并运行'rails server'时，我收到以下错误：
Could not find json-1.8.1 in any of the sources
Run `bundle install` to install missing gems.
当我运行'bundle install'时，它会执行某些操作，但会出现以下错误：
An error occurred while installing json (1.8.1), and Bundler cannot continue.
Make sure that `gem install json -v '1.8.1'` succeeds before bundling.
当我运行gem install json -v'1.8.1'时，我收到以下错误：
Error installing json:
ERROR: Failed to build gem native extension.

根据this answer，你需要ruby开发包（ruby-dev）。
如果您使用Debian / Ubuntu，可以使用
进行安装sudo apt-get install ruby-dev
如果没有，您需要相应的命令来安装操作系统的软件包。
