在 Mac OS 上安装 Nokogiri gem 时出错 X

Question

我试图在我的 Mac OSx 上安装 Rally 和 bugzilla 的连接器。当运行安装脚本时，它会尝试安装 gems 并查找我机器上已经存在的 libxml2。

当它尝试安装 nokogiri 时会发生这种情况。

这是成绩单：

Gem files will remain installed in /Library/Ruby/Gems/2.0.0/gems/nokogiri-1.6.1 for inspection.

我尝试了很多选项，例如通过运行下面的命令安装命令行工具。 xcode-select --install

将符号链接添加到 gcc 编译器

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

这两天我一直在挣扎。非常感谢任何帮助。

Answer 1

如果您使用的是 brew，请在终端中使用：

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

如果这不起作用，请检查“Installing Nokogiri on OSX 10.10 Yosemite”

Answer 2

解决了命令

的问题

sudo ARCHFLAGS="-arch x86_64" gem install nokogiri -v '1.6.1'

感谢 mohamed abd 指出的 link。

sudo gem install nokogiri --no-rdoc --no-ri
