gem install libv8 -v '5.3.332.38.1' ... 安装 libv8 时出错：错误：无法构建 gem 原生扩展

Question

有什么想法/建议吗？

**** 进一步更新：**** 2.3.1 agxxx-xxxight 2290-fix-claim-button % ruby​​ -e 'puts Gem::Platform.local' x86_64-darwin-13

我有 2 台机器，我正在尝试在其上安装 lib v8.... 现在出现相同的错误（不管 darwin v.）
1 一个 mac 桌面（使用 x86_64-darwin-13 但另一个使用 darwin-16）。最初，我认为问题与 darwin-13 有关，但现在无论如何都会遇到同样的问题）。

我已经尝试了许多重新安装和升级 OSX 和 xcode 的解决方案。

Mac OX Sierra 10.12.3 xcode 8.2.1

我看到类似的堆栈溢出，但提到了 ruby​​racer，但不确定这是否与此有关？ Error installing libv8: ERROR: Failed to build gem native extension

这是我的错误：

gem install libv8 -v '5.3.332.38.1' 构建原生扩展。这可能需要一段时间... 错误：安装 libv8 时出错： 错误：无法构建 gem 原生扩展。

Answer 1

试试这个（需要 Homebrew）：

brew install v8
gem install libv8 -- --with-system-v8

对于特定版本：

gem install libv8 -v '5.3.332.38.1' -- --with-system-v8

但我假设版本号需要与 v8 的 Homebrew 公式版本相匹配。
