Question

我正在尝试通过Yosemite上的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。我收到了与Nokogiri有关的错误：

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...
Building nokogiri using packaged libraries.
ERROR:  Error installing nokogiri:
    ERROR: Failed to build gem native extension.

错误消息是：

Answer 1

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

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

并使用以下内容安装nokogiri

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

Answer 2

我使用macports而不是自制软件来工作。我的配置：

安装最新的Xcode Beta（撰写本文时为Beta 3）。
xcode-select --switch /Applications/Xcode-Beta3
根据安装说明here
sudo port install libxml2 libxslt
gem install nokogiri -- --with-iconv-include=/opt/local/include/

有点令人费解，但之后一切都很好。
