mac 上安装 therubyracer 0.12.2 依赖于 libv8 3.16.14.13 安装日志如下: Building native extensions. This could take a while... ERROR: Error installing therubyracer: ERROR: Failed to build gem native extension.

To see why this extension failed to compile, please check the mkmf.log which can be found here:

我在 debian 上安装没有一点问题,,,,,

试试这个方法:

brew tap homebrew/dupes 
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 '0.12.2' # any specify version

有两种解决方法:

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

或者 brew install v8-315; brew link v8-315 --force did the trick for me.

今天我也遇到了这个问题,解决方法

brew tap homebrew/versions
brew install v8-315

gem install libv8 -v '3.16.14.13' -- --with-system-v8
gem install therubyracer -- --with-v8-dir=/usr/local/opt/v8-315

bundle install

#4 楼 @rikiwong 这个我试一下,上面那两个试了不成功。

#4 楼 @rikiwong 多谢,用这个方法安装成功了,

#4 楼 @rikiwong 感谢,mac 10.11.4 通过此方法解决了问题。非常感谢。
