Question

这是我运行bundle install

时遇到的错误

Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

Gem files will remain installed in /Users/sam/.rvm/gems/ree-1.8.7-2012.02@global/gems/unf_ext-0.0.6 for inspection.
Results logged to /Users/sam/.rvm/gems/ree-1.8.7-2012.02@global/gems/unf_ext-0.0.6/ext/unf_ext/gem_make.out
An error occurred while installing unf_ext (0.0.6), and Bundler cannot continue.
Make sure that `gem install unf_ext -v '0.0.6'` succeeds before bundling.

看起来缺少g ++ 4.6。

which g++会返回/usr/bin/g++，但which g++-4.6不会返回任何内容。

我确实安装了Xcode Developer Tools。我不确定该怎么做。如何才能使捆绑安装成功？

使用jruby安装正常。似乎是我正在使用的ree版本的问题。

gem install unf_ext -v'0.0.6'在Mountain Lion mac上失败
