Question

我最近从github派了一个存储库，然而，当我尝试运行“bundle install”时，我得到以下错误输出：

Robert-Quinns-MacBook-Pro:~ robertquinn$ gem install therubyracer

ERROR:  Error installing therubyracer:

以下是我尝试过的一些事情：

gem uninstall libv8
brew install v8
gem install therubyracer

以及：

RUBYOPT=-rrubygems gem install therubyracer

有什么想法吗？

修改

输入以下命令后：

$ brew tap homebrew/dupes
$ brew install apple-gcc42

以下是完整输出，包括这些命令的结果：

Answer 1

由于您的系统上没有编译器，因此失败了。

安装gcc编译器

例如：https://github.com/kennethreitz/osx-gcc-installer

或（自制）：

$ brew tap homebrew/dupes
$ brew install apple-gcc42

无法安装therubyracer
