安装nokogiri安装了Mac OS X 10.8.2 XCode

试图在Mountain Lion上安装nokogiri。 我使用的是ruby 1.8.7，但刚刚升级到1.9.3但它阻止了捆绑安装工作。

顺便说一下，我可以通过卸载ruby 1.9.3并恢复到1.8.7来解决这个问题。 然而，这显然是一个次优的解决方案，因为我不希望在剩下的时间里被卡在1.8.7上……

Make sure that `gem install nokogiri -v '1.5.5'` succeeds before bundling. 

我已经下载了XCODE，包括开发人员工具，所以我不知道为什么它不会安装nokogiri ……

当我尝试直接安装nokogiri时，我得到：

Answer 1

经过简短的研究，我发现通过创建符号链接可以简单地解决什么问题

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

对我有用也希望你

 gem install nokogiri Building native extensions. This could take a while... ERROR: Error installing nokogiri: ERROR: Failed to build gem native extension. /Users/morozovm/.rvm/rubies/ruby-1.9.3-p327/bin/ruby extconf.rb checking for libxml/parser.h... *** extconf.rb failed *** bash-3.2$ sudo ln -s /usr/bin/gcc /usr/bin/gcc-4.2 Password: bash-3.2$ gem install nokogiri Building native extensions. This could take a while... Successfully installed nokogiri-1.5.6 1 gem installed 

Answer 2

试试这些。 我遇到了同样的问题，它对我有用。 首先安装libxml2，然后再次运行bundler。

  brew install libxml2 brew link libxml2 

资料来源： http ： //decielo.com/articles/11/rails-3-on-lion-hey-ho-lets-go

更新：

我希望你安装了自制软件。 如果您没有自制软件，那么我建议您安装自制软件，然后安装libxml2然后再安装。 如果您没有自制软件，请不要使用mac端口。

更新：

这不是命令行工具的问题。 它在libxml失败了。 尝试阅读错误，你会看到

  checking for libxml/parser.h... *** extconf.rb failed *** 

这就是问题所在

Answer 3

我认为这是错误消息中最重要的一点：

 warning: Insecure world writable dir /usr/local in PATH, mode 040777 

构建过程的某些部分抱怨该目录具有权限，以便任何人都可以写入它。 你可以试着追捕它 – 或者你可以解决它。
