无法在 OS X Mavericks 中安装 gem 'therubyracer'

Question

我是 mac 新手，并尝试 bundle install 克隆的 rails 存储库。我在安装 libv8 gem 时遇到错误，谷歌搜索并找到了解决方案并做到了

brew install libv8
gem install libv8 -- --with-system-v8

接下来我被thresracer gem击中了，完整的痕迹如下

我认为这是小牛队的问题。

Answer 1

现在安装 v8 后尝试重新安装 ruby​​。

rvm reinstall 2.0

然后用gem install therubyracer安装rubyracer

Answer 2

你可能想试试我在这个问题中总结的内容："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 Mavericks 推出以来，我一直在处理同样的问题 :)

Answer 3

抱歉，我不知道是什么解决了我的问题。我尝试了一切，它得到了修复。

我使用 macports 安装 gcc47，而不是自制软件。（在我的慢速 512kbps 连接中安装花了将近 2 天时间）

然后我将 therubyracer 的版本更改为'0.12.0'

我不知道是哪个解决了我的问题。

Answer 4

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 对我有用。也许将您的 ruby​​ 2.0.0-p125 升级到 2.0.0-rc2（2.0 已经高于 p353）

如果您使用的是 rbenv：

rbenv install 2.0.0-rc2
rbenv rehash
rbenv shell 2

bundle install

Answer 5

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
