如何安装json gem - 无法构建gem原生扩展 [英] How to install json gem - Failed to build gem native extension

问题描述

我试图在我的ubuntu linux服务器上部署一个rails应用程序。我使用capistrano和bundler，当它安装到gems时，它会失败，并显示以下错误信息：

 安装json（1.7.7 ）与原生扩展
 Gem :: Installer :: ExtensionBuildError：错误：无法构建gem本机扩展。

我正在运行ruby enterprise版本1.8.7，不能升级红宝石，而没有很多工作升级其他网站，所以现在不是一种选择。我尝试了apt-get install ruby​​-dev，但它没有帮助（我不确定这是否是正确的事情）。

解决方案

我想你需要安装这些包之一：

  $ apt-file search limits.h | grep'linux / limits.h'
 linux-headers-2.6.32-5-common：/usr/src/linux-headers-2.6.32-5-common/include/linux/limits.h 
 linux-headers-2.6.32-5-common-openvz：/usr/src/linux-headers-2.6.32-5-common-openvz/include/linux/limits.h 
 linux-headers- 2.6.32-5-common-vserver：/usr/src/linux-headers-2.6.32-5-common-vserver/include/linux/limits.h 
 linux-headers-2.6.32-5- common-xen：/usr/src/linux-headers-2.6.32-5-common-xen/include/linux/limits.h 
 linux-libc-dev：/usr/include/linux/limits.h 
  

I'm trying to deploy a rails app to my ubuntu linux server. I'm using capistrano and bundler and when it gets to installing gems it fails with this error:

Installing json (1.7.7) with native extensions 
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

I am running ruby enterprise edition 1.8.7 and can't upgrade ruby without a lot of work upgrading other sites so that's not an option right now. I tried apt-get install ruby-dev but it didn't help (I'm not sure that was the right thing anyway).

解决方案

I think you need to install one of this packages :

$ apt-file search limits.h | grep 'linux/limits.h'
linux-headers-2.6.32-5-common: /usr/src/linux-headers-2.6.32-5-common/include/linux/limits.h
linux-headers-2.6.32-5-common-openvz: /usr/src/linux-headers-2.6.32-5-common-openvz/include/linux/limits.h
linux-headers-2.6.32-5-common-vserver: /usr/src/linux-headers-2.6.32-5-common-vserver/include/linux/limits.h
linux-headers-2.6.32-5-common-xen: /usr/src/linux-headers-2.6.32-5-common-xen/include/linux/limits.h
linux-libc-dev: /usr/include/linux/limits.h
