我是mac的新手并尝试bundle install克隆的rails repo。我在安装libv8 gem时遇到了错误，谷歌搜索并找到了解决方案并做了
brew install libv8
gem install libv8 -- --with-system-v8
接下来，我被一个明星宝石击中，完整的痕迹如下

我认为这是小牛队的问题。

您可能想尝试我在此问题中总结的内容："gem install therubyracer -v '0.10.2'" on osx mavericks not installing
brew install apple-gcc42
sudo ln -s /usr/local/Cellar/apple-gcc42/4.2.1-5666.3/bin/gcc-4.2 /usr/bin/gcc
sudo ln -s /usr/local/Cellar/apple-gcc42/4.2.1-5666.3/bin/g++-4.2 /usr/bin/g++
sudo ln -s /usr/local/Cellar/apple-gcc42/4.2.1-5666.3/bin/cpp-4.2 /usr/bin/cpp
brew uninstall v8 (only in case you installed it with brew)
gem install libv8
gem install therubyracer
让我知道这是否有效！自从小牛队推出以来，我一直在处理同样的问题：）
答案 1 :(得分：5)
抱歉，我不知道是什么解决了我的问题。我正在尝试所有的东西而且它已得到修复。
我使用macports安装了gcc47，而不是自制软件。（在我的慢速512kbps连接中安装需要将近2天）
然后我将therubyracer的版本改为'0.12.0'
我不知道哪个问题得到解决。
答案 2 :(得分：1)
现在安装v8后尝试重新安装ruby。
rvm reinstall 2.0
然后用gem install therubyracer
答案 3 :(得分：0)
当我从OSX Mountain Lion升级到OSX Mavericks时，我遇到了同样的问题。
从ruby-1.8.7-p354升级到ruby-1.8.7-375对我来说是个窍门。也许将你的ruby 2.0.0-p125升级到2.0.0-rc2（2.0已高于p353）
如果您使用的是rbenv：
rbenv install 2.0.0-rc2
rbenv rehash
rbenv shell 2
bundle install
答案 4 :(得分：0)
gem uninstall libv8
brew rm v8
brew tap homebrew/dupes
brew install apple-gcc42
brew tap homebrew/versions
brew install v8-315
brew link --force v8-315
gem install libv8 -- --with-system-v8
gem install therubyracer
