Question

我正在运行Mac OSX Snow Leopard，这个问题是由最近的train wreck引起的，我在其中更新了没有RVM的ruby。我试图正确安装/运行RVM，但我无法让它工作。

我无法安装sqlite3-ruby gem。我得到以下错误：安装sqlite3-ruby时出错：错误：无法构建gem原生扩展。

我该如何解决这个问题？

Answer 1

卸载sqlite3 gem然后再试一次 - 我好像记得sqlite3和sqlite3-ruby不兼容。否则，将结果文件附加到您的问题中，这样我们就可以看到编译发生时出了什么问题。

Answer 2

您需要安装Xcode。您可以免费下载developer.apple.com。

Answer 3

如果没有安装sqlite3 gem，我的错误几乎相同。卸载带有macports的sqlite3（以及依赖项）。卸载后，sqlite3-ruby安装工作正常。
