问题描述

我正在运行：

• Windows 8.1（64位）


• Ruby：ruby 1.9.3p545（2014-02-24）[i386-mingw32]
  
• gem：1.8.2
  

  
 D：\GIT \calabash> gem install json -v'1.8.3'

解决方案

回应，但可能会帮助其他人。安装json'1.8.3'需要包'libgmp3-dev'。

使用以下步骤：

  sudo apt-get install libgmp3-dev 
 
 gem install json -v'1.8.3'
  

I am trying to install gem json and getting error for json.

I'm running:

• Windows 8.1 (64 bit)
• Ruby: ruby 1.9.3p545 (2014-02-24) [i386-mingw32]
• gem: 1.8.2

D:\GIT\calabash>gem install json -v '1.8.3'
Building native extensions.  This could take a while...
The system cannot find the path specified.

解决方案

Its a late response, but may it helps someone else. to install json '1.8.3' it requires packages 'libgmp3-dev'.

Use following steps:

sudo apt-get install libgmp3-dev

gem install json -v '1.8.3'
