在优胜美地上安装Nokogiri [重复]

Question

这个问题在这里已有答案：

• 在Yosemite Mac OS X 10.10 10答案中 缺少安装nokogiri libiconv的失败

我试图在Yosemite上通过RVM安装Ruby on Rails。 但是，当我尝试运行“捆绑安装”时，一切似乎都有效，我发现有关Nokogiri的错误：

pauls-air:~ paulmcguane$ gem install nokogiri -- --with-xml2-include=/usr/local/Cellar/libxml2/2.9.1/include/libxml2 --with-xml2-lib=/usr/local/Cellar/libxml2/2.9.1/lib --with-xslt-dir=/usr/local/Cellar/libxslt/1.1.28 --with-iconv-include=/usr/local/Cellar/libiconv/1.13.1/include --with-iconv-lib=/usr/local/Cellar/libiconv/1.13.1/lib

This could take a while...

ERROR:  Error installing nokogiri:

错误消息是：

Answer 1

我刚刚完成了Rails和Ruby的完整安装以及你需要的一切。 我按照这些步骤。

https://gorails.com/setup/osx/10.10-yosemite

并使用以下安装nokogiri

xcode-select --install
gem install nokogiri
bundle config build.nokogiri --use-system-libraries
bundle install

Answer 2

我使用macports而不是自制软件工作。 我的配置：

1. 安装最新的Xcode Beta（撰写本文时为Beta 3）。
2. xcode-select --switch /Applications/Xcode-Beta3
3. MacPorts的内置/从源代码安装，每安装说明这里
4. sudo port install libxml2 libxslt
5. gem install nokogiri -- --with-iconv-include=/opt/local/include/

有点复杂，但在那之后一切都很好。
