Nokogiri(在 Ubuntu 上)的强大安装过程是什么? [英] What is a robust installation process for Nokogiri (on Ubuntu)?

问题描述

我尝试在我的 Ubuntu 12.04 系统上安装 Nokogiri，并得到一个错误消息libxslt is missing"，但是 libxslt-dev 和 libxml2-dev 已安装.

I tried to install Nokogiri on my Ubuntu 12.04 system, and got an error that said "libxslt is missing", but the libxslt-dev and libxml2-dev are installed.

是否有可靠的安装过程?如何检查依赖库的链接?

Is there a robust installation process? How can I check the links to dependent libraries?

我使用了 RVM，并且也安装了 RVM pkg.

I used RVM, and the RVM pkg is installed too.

推荐答案

我也遇到了与 rvm 相同的问题，尽管我按照文档做了以下操作:

I have also experienced the same problem with rvm, even though I had done the following, as per documentation:

• 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:

The only way I could get this solved was, after a lengthy investigation:

• 卸载ruby安装:rvm remove 1.9.3
• 如果您以前做过 rvm，请从 ~/.rvm/usr/lib 中删除所有 libxslt* 和 libxml2* 库pkg ...
• 重新安装 ruby​​:rvm install 1.9.3

• Uninstall the ruby installation: rvm remove 1.9.3
• Delete all libxslt* and libxml2* libs from ~/.rvm/usr/lib if you had previously done rvm pkg ...
• Reinstall ruby: rvm install 1.9.3

在apt-get 命令之后重新安装 似乎是让它工作的唯一方法.此外，确保使用 rvm pkg 安装的库不会干扰也有帮助.

Reinstalling after the apt-get commands seems to be the only way of getting this to work. Also, ensuring the libs installed with rvm pkg don’t interfere helped.

当其他一切都失败时...

如果其他一切都失败了并且您绝对需要安装 gem，您还可以通过应用一个简单的补丁来重建 nokogiri — 前提是您已安装所有构建工具，并注意这将安装最新且可能不稳定的代码:

If everything else fails and you absolutely need the gem installed, you can also rebuild nokogiri by applying a simple patch — provided that you have all build tools installed, and with the caveat that this will install the latest and potentially unstable code:

• git clone git://github.com/sparklemotion/nokogiri
• 获取补丁从此要点并将其保存为x86_64.patchnokogiri 文件夹.
• 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 gem install pkg/nokogiri--x86_64-linux.gem
安装 gem

• git clone git://github.com/sparklemotion/nokogiri
• get patch from this gist and save it as x86_64.patch in the nokogiri folder.
• Apply patch: patch -p1 < x86_64.patch
• Rebuild: rake native gem — this should build the gem in the pkg/ folder
• Install the gem using gem install pkg/nokogiri-<version>-x86_64-linux.gem
