在Mac 10.9 / Rails 3.2.11中安装therubyracer gem时出现错误

Question

有什么想法，为什么我不能在Mac 10.9和Rails 3上安装therubyracer gem？

Installing therubyracer (0.11.3)

An error occurred while installing therubyracer (0.11.3), and Bundler cannot continue.
Make sure that `gem install therubyracer -v '0.11.3'` succeeds before bundling.

任何解决方法都将不胜感激。

回复：解决方法 - 不要使用 therubyracer。您可以在任何没有预装 JS 引擎的环境中（例如 Linux）安装 node.js 以替代。标准 Rails 应用程序在 OS X 和 Windows 上不需要它。 - PinnyM

除了上述的解决方法之外，你是否还有其他的解决方案呢？如果有，请提供答案。 - miked

不同的OSX和Rails版本，但最终我们不得不构建自己的libv8（3.16.14.7）才能使一切正确捆绑 - 已经过去了大约一年，我不记得具体情况了。我们在开发环境中携带着那个libv8 - 在Linux生产环境中没有问题。 - dwilkins

Answer 1

尝试使用 bundle update

如果不起作用，尝试

gem uninstall libv8
brew install v8
gem install libv8 -- --with-system-v8
gem install therubyracer -v '0.11.3' -- --with-system-v8

Answer 2

你在Gemfile中声明了什么？

试试这个：

gem 'therubyracer'，platforms: :ruby

你的建议更适合作为评论，不太能称为答案。 - whizcreed

我不同意你的观点：在许多情况下，它只是解决问题而无需将Node.js安装到系统中。如果解决方案很简单，这并不意味着需要在评论中建议它，无论如何，祝您投票成功 :-( - Zen
