OSX Yosemite和Xcode 6安装后的Ruby gem安装错误

Question

我尝试在安装优胜美地之前安装一个像我一样的宝石,但现在我收到一个错误:

/Library/Ruby/Site/2.0.0/rubygems/ext/builder.rb:159:in"synchronize":错误:无法构建gem原生扩展.(宝石::内线:: BuildError)

错误:无法构建gem原生扩展.

僵局; 递归锁定

这是我写的命令:

sudo gem install mysql2

这是它出现在终端中的消息:

我使用的是OSX 10.10和Xcode 6 Beta.

你们中的任何人都知道如何处理这件事吗？

我遇到过同样的问题。使用 RVM 降级到 ruby​​ 1.9.3 解决了我在 10.10 Yosemite 上的问题 - 以下是采取的步骤：

$ \curl -sSL https://get.rvm.io | bash
$ source /Users/shedali/.rvm/scripts/rvm
$ rvm install 1.9.3 --with-gcc=clang
$ gem install [packagename]
