在Mac OS X上安装Nokogiri gem时出错

I was trying to install a connector for Rally and bugzilla on my Mac OSx. While running the install script, it tries to install the gems and it looks for the libxml2 which is already present on my machine.

我试着在我的Mac OSx上安装一个连接器用于集会和bugzilla。在运行安装脚本时，它尝试安装gems，并查找在我的机器上已经存在的libxml2。

This happens when it tries to install nokogiri.

当它试图安装nokogiri时就会发生这种情况。

This is the transcript:

这是记录:

I tried so many options like installing the command line tools by running the below command. xcode-select --install

我尝试了很多选项，比如通过运行下面的命令来安装命令行工具。xcode-select——安装

Adding the symbolic links to gcc compliler

向gcc遵从者添加符号链接

sudo ln -s /usr/bin/llvm-gcc /usr/bin/gcc-4.2

I have been struggling for the past two days. Any help is highly apperciated.

过去两天我一直在挣扎。任何帮助都是高度恰当的。

#1

If you are using brew use this in the terminal:

如果你正在使用brew应用于终端:

brew unlink gcc-4.2      # you might not need this step
gem uninstall nokogiri
xcode-select --install
gem install nokogiri

If this didn't work please check "Installing Nokogiri on OSX 10.10 Yosemite"

如果不成功，请检查“在OSX 10.10 Yosemite上安装Nokogiri”
