Nokogiri本机扩展无法构建(不是libxml2或libxslt缺少问题)

Question

正如标题所说,它似乎没有失败,因为缺少libxml2或libxslt.我不确定该怎么做错误.(得到它？因为问题是在制作过程中？嘿嘿......)

Anywho,这是我得到的输出.任何想法,将不胜感激:

对于上下文,我昨晚从Ubuntu 12.04升级到12.10.我之前在这个盒子上构建了Nokogiri本机扩展,但我不知道它是否是相同的版本.

我还检查了我在第二篇文章中指定的所有软件包" 错误安装nokogiri 1.5.0 with rails 3.1.0和ubuntu "无济于事.

Answer 1

花了我一些时间来弄清楚如何追加cflags.这是我对nokogiri 1.4.7的命令:

sudo gem install  nokogiri -v '1.4.7' -- --with-cflags=\"-Wformat-nonliteral -Wno-format-security\"

Answer 2

您是否尝试过为nokogiri安装以下依赖项？

# nokogiri requirements
sudo apt-get install libxslt-dev libxml2-dev
sudo gem install nokogiri

Answer 3

如果您正在尝试安装Nokogiri <1.5.4,那么在Ubuntu 12等强化的Debian系统上你会遇到问题.

有关根本问题的详细信息,请访问:https://github.com/sparklemotion/nokogiri/issues/680

您应该能够升级到1.5.4或更高版本并安装没有此问题.

或者,您应该能够在gem-install时设置CFLAGS环境变量以包含字符串:

-Wno-error=format-security

要么

-Wformat-nonliteral -Wno-format-security

祝好运!
