【问题描述】：

我正在尝试建立一个现有项目。当我运行 bundle install 时，我在 therubyracer gem 上收到以下错误：

An error occurred while installing therubyracer (0.10.2), and Bundler cannot continue.
Make sure that `gem install therubyracer -v '0.10.2'` succeeds before bundling.

【问题讨论】：

"gem install therubyracer -v '0.10.2'" on osx mavericks not installing 的可能重复项

您必须使用 g++ 4.2 编译libv8，详情请参阅链接问题。

【参考方案1】：

使用 ruby​​ 2.2.0，它应该可以工作。

对我来说，它不适用于具有任何可能设置的 ruby​​ 2.1.x。 使用 ruby​​ 2.2.0 运行顺利。

【参考方案2】：

按照以下步骤操作：

Terminal

gem uninstall libv8

Gemfile

gem 'therubyracer'
bundle install

就是这样。你的 libv8 和 therubyracer 版本不匹配，所以你得到了那个错误。
