json gem安装包安装错误

Question

当我尝试进行包安装时，出现以下json错误。软件包安装没有完成。是什么赋予了？

Errno::EACCES: Permission denied - /usr/local/Cellar/ruby/1.9.3-p194/lib/ruby/gems/1.9.1/gems/json-1.7.5/.gitignore 
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. 

>>$ gem install json -v '1.7.5' 
ERROR: While executing gem ... (Errno::EACCES) 
Permission denied - /usr/local/Cellar/ruby/1.9.3-p194/lib/ruby/gems/1.9.1/gems/json-1.7.5/.gitignore 

编辑：sudo的安装命令提供了以下错误：

>>$ sudo gem install json -v '1.7.5' 
Building native extensions. This could take a while... 
ERROR: Error installing json:

Answer 3

你需要安装ruby1.8-dev而不是j ust ruby​​1.8，你错过了开发标题。

如果在OSX：

sudo install ruby1.8-dev 

如果在UNIX

sudo aptitude install ruby1.8-dev 

或

sudo apt-get install ruby1.8-dev 

进入你的目录与RubyGems的源代码并运行：该运行后 sudo ruby setup.rb ：

如果在OSX：

sudo gem install json -v '1.7.5' 

一些UNIX系统可能需要宝石version命令才能正常工作，所以你应该运行：

sudo gem1.8 install json -v '1.7.5'
