ruby-on-rails - 在fedora 20上安装TheRubyRacer gem时出错

Question

我正在做一个需要therubyracer的项目。当我进行 bundle 安装时，当 bundle 器尝试安装therubyracer时，会出现以下错误消息。

Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

Gem files will remain installed in /home/anupam/.gem/ruby/gems/therubyracer-0.12.1 for inspection.
Results logged to /home/anupam/.gem/ruby/gems/therubyracer-0.12.1/ext/v8/gem_make.out
An error occurred while installing therubyracer (0.12.1), and Bundler cannot continue.
Make sure that `gem install therubyracer -v '0.12.1'` succeeds before bundling.

当我运行gem install therubyracer -v'0.12.1'或没有该版本时，它仍然会失败。

我是 ruby 的新手，所以我不太了解发生了什么或为什么会失败。

任何帮助对此表示感谢。

我在Fedora 24 x64上遇到了同样的问题，并且sudo dnf -y install gcc-c++解决了我的问题
