Nokogiri(在Ubuntu上)的强大安装过程是什么？

Question

我想我的Ubuntu 12.04系统上安装引入nokogiri,并得到一个错误,说:" libxslt is missing",但libxslt-dev和libxml2-dev安装.

有一个强大的安装过程吗？如何检查依赖库的链接？

我使用了RVM,也安装了RVM pkg.

我也遇到过与rvm相同的问题,即使我按照文档完成了以下操作:

• sudo apt-get install libxslt-dev libxml2-dev
• rvm pkg libxml2 和 rvm pkg libxslt

经过长时间的调查,我能解决这个问题的唯一方法是:

• 卸载ruby安装: rvm remove 1.9.3
• 如果您以前完成了,请删除所有libxslt*和libxml2*库~/.rvm/usr/librvm pkg ...
• 重新安装ruby: rvm install 1.9.3

重新安装后,该apt-get命令似乎得到这个工作的唯一途径.另外,确保安装的lib rvm pkg不会干扰.

当其他一切都失败了......

如果其他一切都失败并且你绝对需要安装gem,你也可以nokogiri通过应用一个简单的补丁来重建- 只要你安装了所有的构建工具,并且需要注意这将安装最新且可能不稳定的代码:

• git clone git://github.com/sparklemotion/nokogiri
• 从这个要点获取补丁并将其保存x86_64.patch在nokogiri文件夹中.
• 应用补丁: patch -p1 < x86_64.patch
• 重建:rake native gem- 这应该在pkg/文件夹中构建gem
• 使用安装gem gem install pkg/nokogiri-<version>-x86_64-linux.gem
