我在升级到Xcode 4.3后(删除了旧版本的Xcode)无法安装autotest-fsevent gem。通过“首选项”>“下载”>“组件”选项卡安装了命令行工具。
操作系统为osx 10.7.3,rvm版本为1.10.2,ruby版本为1.9.3-rc1,bundler版本为1.0.22。
$ bundle
Installing autotest-fsevent (0.2.7) with native extensions

Gem files will remain installed in /Users/doc/.rvm/gems/ruby-1.9.3-rc1@global/gems/autotest-fsevent-0.2.7 for inspection.

An error occured while installing autotest-fsevent (0.2.7), and Bundler cannot continue.
Make sure that `gem install autotest-fsevent -v '0.2.7'` succeeds before bundling.
README文件中只是简单说明需要使用Xcode。
我已经选择了正确的Xcode.app:
$ xcode-select -print-path
/Applications/Xcode.app/Contents/Developer
还有其他人遇到这个问题吗?有什么办法可以解决吗?
