我正在全新安装 OSX 10.9 Mavericks 和 XCode 5.0.1。当我尝试在我的项目中运行 bundle install 时，安装 libv8 gem 失败。这是输出：

ERROR:  Error installing libv8:

做的时候也是

gcc -v

我来了

我尝试通过自制软件安装 gcc，但这没有帮助。还有哪些可能的解决方案？

标签： ruby macos gcc libv8 osx-mavericks

【解决方案1】：

切换到旧版本的 Xcode 对我不起作用。相反，我使用了来自 github 的最后一个 libv8 修复：https://github.com/cowboyd/libv8/issues/107

完美运行。

【讨论】：

按照 cmets 中的步骤在本地编译/安装，它对我有用。
这是经过多次爬网后终于奏效的。对于其他遇到 OSX10.9 问题的人，我还手动安装了 Mavericks XCODE 5.1 命令行工具 - 以前你可以从 xcode 中安装它，但现在我相信你需要转到“苹果下载”开发人员”网站developer.apple.com/downloads/… 并使用您的 Apple ID（无需开发帐户）在 10.9 选项卡下下载命令行工具。

【解决方案2】：

好的，安装旧版本的 Xcode (4.6.3) 并将命令行工具版本更改为 Xcode 首选项中的旧版本即可解决问题。

【解决方案3】：

在 Applications 文件夹中安装 XCode 4.6.3，然后运行

sudo xcode-select --switch /Applications/Xcode4.6.3.app/Contents/Developer

安装完 libv8 后，您可以通过以下方式恢复

sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer
