ruby-on-rails - 安装 nokogiri Mac OS X 10.8.2 XCode 已安装

Question

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的工作。

顺便说一句，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，因为我不想在剩下的时间里被困在 1.8.7 上......

An error occurred while installing nokogiri (1.5.5), and Bundler cannot continue.
Make sure that `gem install nokogiri -v '1.5.5'` succeeds before bundling.

我已经下载了包含开发工具的 XCODE，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：

经过短暂的研究，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

对我有用希望对你也有用

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，然后安装 bundler。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 上失败了。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

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任何人都可以写入的权限。您可以尝试追捕它 - 或者您可以修复它。
