有很多人有类似的问题，我过去在其他机器上也是其中之一，而且那里的解决方案似乎都不起作用——我似乎也有与其他有类似问题的人不同的错误：

Gem files will remain installed in /Users/ecnalyr/.rvm/gems/ruby-2.0.0-p353@canopy/gems/therubyracer-0.12.2 for inspection.
Results logged to /Users/ecnalyr/.rvm/gems/ruby-2.0.0-p353@canopy/extensions/x86_64-darwin-14/2.0.0/therubyracer-0.12.2/gem_make.out

运行时：

gem install therubyracer -v '0.12.2'

或者干脆

bundle install

包含therubyracer在我的 gemfile 中。

我正在运行 Yosemite 10.10.3、Ruby 2.0.0-p353，我已经卸载了所有内容并尝试gem install libv8 -- --with-system-v8了经常出现此类问题的解决方案，但没有找到解决方案。

创建一个临时文件“__debug”为我解决了这个问题。

在终端中运行此命令：

echo '#define _LIBCPP_ASSERT(x, m) ((void)0)' | sudo tee -a /Library/Developer/CommandLineTools/usr/include/c++/v1/__debug > /dev/null

我能够通过重新安装XCode 6.2 的命令行工具（而不是 XCode 6.3 的命令行工具）来解决这个问题。

Stack Overflow 29529455中有更多讨论。
