OSX Yosemite和Xcode 6安装后的Ruby gem安装错误

我在安装Yosemite之前尝试安装一个像我一样的gem，但是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。 （gem::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？

Answer 1

当我通过bitnami安装mysql时遇到同样的问题，看起来你没有所有必需的mysql库。

我使用brewsh并重新安装了mysql

 brew install mysql sudo gem install mysql2 

您还需要在主目录中的.profile文件中加载动态库，您可以通过在.profile文件中添加这些行来实现此目的。

 export PATH=$PATH:$MYSQL export DYLD_LIBRARY_PATH=/Applications/mysql/lib:$DYLD_LIBRARY_PATH 

在上面的两行代码中

/ Applications / mysql / lib，是安装mysql库的路径，在你的mysql库中可能会有所不同，请根据你的环境进行检查和使用

我遇到过同样的问题。 使用RVM降级为ruby 1.9.3在10.10优胜美地上为我解决了问题 – 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]
