雪豹 sqlite3-ruby 安装问题

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​​。我已尝试正确安装/运行 RVM，但无法正常工作。

我无法安装 sqlite3-ruby gem。我收到以下错误：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

在没有安装 sqlite3 gem 的情况下，我遇到了几乎相同的错误。使用 macports（以及依赖项）卸载 sqlite3。卸载后，sqlite3-ruby install 工作正常。

Answer 2

卸载 sqlite3 gem，然后重试——我似乎记得 sqlite3 和 sqlite3-ruby 不兼容。否则，请将结果文件附加到您的问题中，以便我们可以查看编译发生时出了什么问题。

Answer 3

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