我在osx 10.6.7上试图在一个新的rails 3.0.7应用上运行bundle install，并且在尝试构建pg gem时仍然失败。它一直告诉我，我需要开发人员工具。但据我所知，我已安装了开发人员工具。

以下是xcodebuild的版本--version

Xcode 3.2.6 组件版本：DevToolsCore-1809.0; DevToolsSupport-1806.0 BuildVersion：10M2518

以下是失败的pg gem build

任何帮助将非常感激。仅供参考我也尝试用mysql构建应用程序，基本上获得了相同的堆栈。所以我很确定我错过了某种开发人员构建工具，但我只是不知道哪些工具。 ：（

解决方案我在安装Rails应用程序时遇到了完全相同的问题，我安装了自制程序，然后运行

p>

brew install postgresql。

终于正确安装了postgres，问题已解决。

I am on osx 10.6.7 trying to run bundle install on a new rails 3.0.7 app and it keeps failing when trying to build the pg gem. It keeps telling me that I have need the developer tools. But as far as I can tell I have the developer tools installed.

Any help would be immensely appreciated. FYI I also tried building the app with a mysql and essentially got the same stack. So I'm pretty sure I'm missing some sort of developer build tools, but I just don't know which ones. :(

解决方案

I had the exact same problem when running bundle install in a Rails app. I installed homebrew and then ran

brew install postgresql.

That finally installed postgres correctly and the issue was fixed for me.
