在 Mac OS X 10.8.2 上安装 Nokogiri，需要先安装 XCode。

Question

在 Mac OS X 10.8.2 上安装 Nokogiri，需要先安装 XCode。

12

尝试在Mountain Lion上安装nokogiri。我之前使用的是ruby 1.8.7，但现在升级到了1.9.3，结果导致bundle install无法正常工作。

顺带一提，我可以通过卸载ruby 1.9.3并还原到1.8.7来解决这个问题。然而，这显然是一种次优解决方案，因为我不想永远停留在1.8.7上…

我已经下载了包括开发工具的XCODE，所以我不知道为什么它无法安装nokogiri...

当我尝试直接安装nokogiri时，会出现以下错误：

我假设您在尝试在bundle之外直接安装nokogiri时得到了相同的结果？ - Randy Eppinger

我刚刚将安装nokogiri时遇到的错误信息直接添加到答案中。 - Ravin

@ravin 这不是命令行工具的问题。 - Mohit Jain

Ravin，Mohit的回答看起来不错。如果它解决了问题，你应该将其标记为答案。我想知道这个解决方案以备将来参考。 - Randy Eppinger

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

 brew install libxml2
 brew link libxml2

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

更新：

我希望您已经安装了Homebrew。如果您没有安装Homebrew，那么我建议您先安装Homebrew，然后安装libxml2和bundler。如果您没有Homebrew，请不要使用MacPorts。

更新：

这不是命令行工具的问题。它在libxml处失败。尝试阅读错误信息，您会看到。

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

这就是问题所在。

很遗憾，这并没有帮助我（我有一个完全相同的问题）。我已经链接了libxml2和libxslt，但我仍然遇到了@Ravin之前提到的libxml/parser.h错误。还有其他建议吗？ - JP.

你也遇到了同样的错误吗？正在检查 libxml/parser.h... *** extconf.rb 失败 *** - Mohit Jain

我认为这是错误信息中最重要的部分：

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

构建过程的某些部分正在抱怨该目录的权限是任何人都可以写入的。您可以尝试找到它，或者您可以修复它。
