Ruby on rails 在fedora 20上安装TheRubyRacer gem时出错

我正在做一个项目，需要一个机器人。当我安装bundle时，当bundler尝试安装rubyracer时，我会收到以下错误消息

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安装rubyracer-v'0.12.1'或不运行该版本时，它仍然失败

我是ruby的新手，所以我不太明白到底发生了什么，也不明白它为什么会失败

非常感谢您的帮助。

我删除了所有宝石

卸载的ruby

重新安装ruby-devel

安装了ruby和ruby-devel，并使用yum而不是gem安装了rubyracer和libv8

然后我运行bundle安装，gem使用了已经安装的、由yum安装的gem

感谢上帝为fedora的维护者！你们真是太棒了

我知道这听起来很愚蠢，但我确实遇到了问题，而且我似乎缺少gcc-c++软件包。我想他们已经有了

yum安装gcc-c++

成功了

我在Fedora 24 x64上遇到了同样的问题，

sudo dnf-y安装gcc-c++

解决了我的问题

尝试以下操作：

gem安装therubyracer-v'0.12.1'--with-system-v8

没有调试消息。只是一条没有任何提示的直接错误消息[anupam@localhosttherubyracer-0.12.1]$gem安装therubyracer-v“0.12.1”--with-system-v8使用“--with-system-v8”构建本机扩展这可能需要一段时间。。。错误：安装RubyRacer时出错：错误：无法生成gem本机扩展。Gem文件仍将安装在/home/anupam/.Gem/ruby/gems/therubyracer-0.12.1中以供检查。
