Nokogiri gem安装在Capistrano部署中失败 [英] Nokogiri gem install failing in Capistrano deploy

问题描述

尝试通过捆绑器/ capistrano安装Nokogiri时收到错误：

When attempting to install Nokogiri via bundler/capistrano I am receiving the error:

An error occurred while installing nokogiri (1.6.5), and Bundler cannot continue

深入挖掘，我可以看到>> libxml2版本2.6需要.21或更高版本！

Digging deeper I can see >> libxml2 version 2.6.21 or later is required!

该错误消息还会显示，请确保gem install nokogiri -v'1.6.5'

好吧，如您所见，这不是问题：

Well, as you can see this is not a problem:

vagrant@vagrant:~$ gem install nokogiri -v '1.6.5'
Building native extensions.  This could take a while...
Successfully installed nokogiri-1.6.5
1 gem installed

遗憾的是，即使通过了此测试，cap部署仍然会失败，并出现相同的错误。

Sadly, even when this test is passed, the cap deploy still fails with the same error.

安装nokogiri（1.6.5）时发生错误，Bundler无法继续

我已经确保我的virtualbox上安装了最新版本的libxml2。我什至删除了我的项目目录，然后重新启动了服务器：

I have I have ensured the latest version of libxml2 is installed on my virtualbox. I even removed my project directory, and rebooted the server:

$ vagrant ssh
$ sudo apt-get update
$ sudo apt-get upgrade libxml2
$ sudo rm -rf /var/www/rails-devise-capistrano/
$ sudo reboot

我也尝试将其添加到deploy.rb

I have also tried added this to deploy.rb

set :bundle_env_variables, { nokogiri_use_system_libraries: 1 }

这里是捆包错误

推荐答案

我遇到了同样的问题，尝试了很多选择，但是我需要的是这两个库： / p>

I had the same problem and tried a lot of options but what I needed were these two libraries:

libxml2-devel
libxslt-devel

问题是输出总是提到 libxml2 ，但是所需的内容似乎在开发库中。 （我不是很喜欢图书馆和其他东西，所以我不能确切地说出问题是什么。）我使用Cent OS，所以它可能与您的设置有些不同（例如 libxml2-dev libxslt1-开发）。

The thing is the output always mentioned libxml2 but the needed stuff seemed to be in the development library. (I'm not really into libraries and stuff so I can't tell exactly what the porblem was.) I use Cent OS so maybe its a bit different with your setup (something like libxml2-dev libxslt1-dev).
