如果您决定使用较新的therubyracer
gem版本,则不会再出现此问题
否则:
brew tap homebrew/dupes # Thanks Tom
brew install apple-gcc42
export CC=/usr/local/Cellar/apple-gcc42/4.2.1-5666.3/bin/gcc-4.2
export CXX=/usr/local/Cellar/apple-gcc42/4.2.1-5666.3/bin/g++-4.2
export CPP=/usr/local/Cellar/apple-gcc42/4.2.1-5666.3/bin/cpp-4.2
brew uninstall v8

所以我终于在经历了一些挣扎之后才开始工作......感谢Simon和Alvaro。
我有一件事要补充,使用标志--with-system-v8对我不起作用...所以我删除了我的系统v8
brew uninstall v8
并且运行
gem install libv8
如果您已经使用system v8标志运行gem install libv8
,请确保卸载该gem版本(通过运行gem uninstall libv8
来执行此操作)。重要的是你不应该使用brew提供的那个,它似乎不适用于Mavericks(它安装得很好,捆绑器会报告你的捆绑包已经完成,但是你的应用程序尝试使用v8时会失败)。
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
gem install libv8
gem install therubyracer
答案 2 :(得分:10)
我有同样的问题,这对我有用:
therubyracer(0.10.2)&amp; libv8(3.3.10.4)
首先:
brew install apple-gcc42
gcc
,cpp
,g++
)链接到/usr/local/Cellar/apple-gcc42/4.2.1-5666.3/bin/<compiler>
之后,你可以试试这个:
brew install v8
gem install libv8 -v '3.3.10.4' -- --with-system-v8
gem install therubyracer -v 'therubyracer'
或bundle install
进入rails项目目录。答案 3 :(得分:7)
我遇到了同样的问题,一个解决方案目前使用 apple-gcc42 代替 clang 来编译这两个宝石:
brew install apple-gcc42
然后你可以选择在/ usr / bin中为{gcc,g ++,c ++}二进制文件做一些符号链接:
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
实际上 g ++ 就足够了。
或者......您可以使用与自制软件创建的二进制文件对应的路径导出CC / CXX / CPP环境变量。这肯定是一个更清洁的解决方法。
第三种解决方案是下载Xcode 4.6.3并将其安装在 Applications 文件夹中。然后,输入终端:
sudo xcode-select --switch /Applications/Xcode4.6.3.app/Contents/Developer
gem install therubyracer
安装完宝石后,您可以切换回Xcode 5.0:
sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer
答案 4 :(得分:6)
我发现了一种无需安装apple-gcc42即可解决的问题。
如果您收到的错误消息如下所示,这将有效:
clang: error: no such file or directory: '/Users/mscottford/.rbenv/versions/1.9.3-p327/lib/ruby/gems/1.9.1/gems/libv8-3.3.10.4/lib/libv8/build/v8/libv8.a'
然后你应该能够做到以下几点:
brew install v8
bundle install
# after failing create link from brew installed v8 to error location
ln -s /usr/local/Cellar/v8/3.21.17/lib/libv8_base.x64.a /Users/mscottford/.rbenv/versions/1.9.3-p327/lib/ruby/gems/1.9.1/gems/libv8-3.3.10.4/lib/libv8/build/v8/libv8.a
bundle install

正如许多答案中所建议的那样,最简单的方法是使用Apple GCC 4.2编译Ruby Racer原生扩展(而不是使用Xcode安装的版本)。
如果您使用的是MacPorts,则不必手动处理为GCC二进制文件设置符号链接。 port select
命令为您完成。如果您在安装Mavericks后没有更新MacPorts,请执行sudo port selfupdate
。随着MacPorts的最新版本,请尝试以下方法:
# If you don't have it, install the port for Apple's GCC 4.2
sudo port install apple-gcc42
# OR
# If you had apple-gcc42 already (before Mavericks), update it
sudo port upgrade apple-gcc42
# Same result as manual symlinking of GCC in other answers
sudo port select gcc apple-gcc42 && hash -r
# Install therubyracer, will install libv8 gem dependency
# *note* if you have any existing versions of these gems, remove them
gem install therubyracer
# Restore GCC to system default (optional)
sudo port select gcc none && hash -r
通常,此过程(sudo port select gcc [version]
)可以在您想要使用特定GCC版本而不是Xcode安装的版本(Apple LLVM v5适用于10.9 Mavericks / Xcode 5)时使用。

我设法在ruby 2.0.0p353和os x 10.9上安装therubyracer 0.12和libv8 3.16.14.3
libv8需要gcc42
brew install v8
brew install apple-gcc42
sudo ln -sf /usr/local/Cellar/apple-gcc42/4.2.1-5666.3/bin/gcc-4.2 /usr/bin/gcc
sudo ln -sf /usr/local/Cellar/apple-gcc42/4.2.1-5666.3/bin/g++-4.2 /usr/bin/g++
sudo ln -sf /usr/local/Cellar/apple-gcc42/4.2.1-5666.3/bin/cpp-4.2 /usr/bin/cpp
gem install libv8
therubyracer后来需要gcc
brew install gcc49
sudo ln -sf /usr/local/Cellar/gcc49/4.9-20131110/bin/gcc-4.9 /usr/bin/gcc
sudo ln -sf /usr/local/Cellar/gcc49/4.9-20131110/bin/g++-4.9 /usr/bin/g++
sudo ln -sf /usr/local/Cellar/gcc49/4.9-20131110/bin/cpp-4.9 /usr/bin/cpp
的Gemfile
gem 'therubyracer', :require => 'v8', :platforms => :ruby
使用bundle
代替gem install therubyracer
答案 7 :(得分:3)
这应该是一种安全且干净的方法(没有符号链接)来为任何有麻烦的人安装therubyracer。
取自:gem install therubyracer -v 0.11.4 fails on OS X 10.10
安装Xcode(如果您还没有这些版本之一)6.1.1,6.2-beta或6.3-beta和(需要这一个)4.6.3
gem uninstall libv8
如果你还没有这样做
切换到Xcode 4.6.3
sudo xcode-select --switch /Applications/Xcode4.6.3.app/Contents/Developer
gem install libv8 -v '3.11.8.17'
或者与您的版本的therubyracer相关的版本
切换到Xcode 6.1.1,6.2-beta或6.3-beta(或者如果您想尝试当前安装的Xcode,请调整此行,我已经确认了所有这3项工作)
sudo xcode-select --switch /Applications/Xcode6.1.1.app/Contents/Developer
gem install therubyracer -v '0.11.4'
或您尝试安装的版本。

在尝试安装therubyracer 0.12.0以使其与libv8一起使用时,我遇到了几乎相同的错误。这对我有用:

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。
也许尝试从ruby 1.9.3-p194升级到rc1(1.9.3现在高于p484)
假设您使用rbenv:

从小牛升级到约塞米蒂后我遇到了这个问题。问题是我使用旧版本的OSX编译了我的Ruby版本。
如果我跑了
ruby -rubygems -e 'puts Gem::Platform.new(RUBY_PLATFORM)'
我会为优胜美地获得x86_64-darwin-13
而不是x86_64-darwin-14
。
重新安装Ruby I
rvm remove ruby-2.1.1
rvm reinstall --disable-binary 2.1
然后,在尝试了上述所有解决方案之后,我能够毫无错误地运行bundle install
。

我做的是对osx mavericks:
git clone git@github.com:cowboyd/therubyracer.git
然后:
gem build therubyracer.gemspec
gem install therubyracer-0.12.1.gem
此过程下载了libv8的二进制版本并进行了安装。
