osx mavericks没有安装"gem install therubyracer -v'0.10.2"

Question

尝试使用"gem install therubyracer -v'0.10.2'"在小牛上安装therubyracer但是我收到以下错误:

任何人都可以帮我弄清楚如何使这个宝石工作？我安装了命令行工具.

Answer 1

如果您决定使用较新的therubyracergem版本,则不会再出现此问题

除此以外:

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

gem uninstall libv8

gem install therubyracer -v '0.10.2' # specify version

Answer 2

所以我终于在经历了一些挣扎之后才开始工作......感谢西蒙和阿尔瓦罗.

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

跑了

gem install libv8

如果您已经gem install libv8使用系统v8标志运行,请确保卸载该gem版本(通过运行来执行gem uninstall libv8).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).

总结答案,做以下工作对我有用:

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

Answer 3

我有同样的问题,这对我有用:

therubyracer(0.10.2)&libv8(3.3.10.4)

首先:

• brew install apple-gcc42
• 你必须在编译器的所有二进制文件(链接gcc,cpp,g++),以/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'或者bundle install进入rails项目的目录.

Answer 4

我只是遇到了同样的问题,目前有一个解决方案是使用apple-gcc42而不是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

事实上,g ++应该足够了.

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,进入终端:

sudo xcode-select --switch /Applications/Xcode4.6.3.app/Contents/Developer
gem install therubyracer

安装gem后,您可以切换回Xcode 5.0:

sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer

Answer 5

我找到了一个没有安装apple-gcc42的解决方法.

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
