问题描述
正如标题所述，它似乎没有失败，因为缺少libxml2或libxslt.我不太确定该怎么做 该错误. (明白吗?因为问题出在制造过程中?呵呵...)
As the title says, it doesn't seem to be failing because libxml2 or libxslt is missing. I'm not really sure what to make of the error. (Get it? Because the issue is during make? hehe...)
任何人，这是我得到的输出.任何想法将不胜感激:
Anywho, here's the output I'm getting. Any ideas would be appreciated:

对于上下文，我昨晚从Ubuntu 12.04升级到12.10.我以前曾在此盒子上构建过Nokogiri本机扩展，尽管我不知道它是否是同一版本.
For context, I upgraded from Ubuntu 12.04 to 12.10 last night. I had previously built the Nokogiri native extension on this box, though I do not know if it was the same version or not.
我还检查了我是否具有在"在带滑轨3.1.0和ubuntu的系统上安装nokogiri 1.5.0时出错" 无济于事.
I also checked that I have all packages specified in the second post on "error installing nokogiri 1.5.0 with rails 3.1.0 and ubuntu" to no avail.
推荐答案
如果您要安装Nokogiri< 1.5.4，在诸如Debian Ubuntu 12之类的强化Debian系统上会遇到问题.
If you're trying to install Nokogiri < 1.5.4, you'll have problems on hardened Debian systems like Ubuntu 12.
有关此基本问题的详细信息在这里: https://github.com/sparklemotion/nokogiri/Issues/680
Details on the underlying issue are here: https://github.com/sparklemotion/nokogiri/issues/680
您应该能够升级到1.5.4或更高版本，并且安装时不会出现此问题.
You should be able to upgrade to 1.5.4 or later and install without this problem.
或者，您应该能够在gem-install时将CFLAGS环境变量设置为包含字符串:
Alternatively, you should be able to set the CFLAGS environment variable at gem-install time to include the string:
-Wno-error=format-security
或
-Wformat-nonliteral -Wno-format-security
祝你好运！
