Question

我试图使用ThoughtBot的Suspenders gem开始个人项目，并在运行bundle install时遇到capybara-webkit的错误。谷歌出现了一些类似的报道，大多数似乎是通过按照capybara-webkit GitHub here的说明安装Qt解决的（我注意到指令是针对OSX 10.9 Mavericks和10.8 Mountain Lion，而我＆＃39;我使用10.10 Yosemite，但我没有特别注意10.10的任何内容。

如果在构建时出现错误，则会出现致命错误： QObject：没有这样的文件或目录，您可能正在尝试构建反对Qt3，或Qt4的早期版本。确保qmake中你的PATH链接到Qt4.8。
which qmake # to see where it links
rm `which qmake` # IF it is linking to an old version

OSX说明如下：

访问QT网站（一般下载站点，4.8.6安装程序）和下载Qt库4.8.6 for Mac（185 MB）和调试库（480 MB）。

所以我在链接下载并安装了两个Qt库。我从命令行获得以下输出：

Davids-MBP:app david$ which qmake
/usr/bin/qmake
Davids-MBP:app david$ qmake --version
QMake version 2.01a
Using Qt version 4.8.6 in /Library/Frameworks

然而，当我从我的应用程序中运行bundle install时，我得到了这个输出：

Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

Gem files will remain installed in /Users/david/.rbenv/versions/2.2.1/lib/ruby/gems/2.2.0/gems/capybara-webkit-1.5.0 for inspection.

An error occurred while installing capybara-webkit (1.5.0), and Bundler cannot continue.
Make sure that `gem install capybara-webkit -v '1.5.0'` succeeds before bundling.

我回去并删除了Qt，然后尝试根据链接文档从源代码构建它。这个过程如此错误：

有人可以帮忙吗？

我通过rbenv使用ruby 2.2.1。

检查App Store以查看您最近是否更新到命令行工具6.3。如果是这样，您需要安装6.3.1，该版本现已在Apple的开发者网站上提供：https://developer.apple.com/downloads/index.action#

此外，这是帮助我解决此问题的另一个StackOverflow问题： Missing C++ header <__debug> after updating OSX Command Line Tools 6.3
