在OSX 10.11 El Capitan上安装therubyracer gem

Question

bundle install 失败了 Make sure that `gem install therubyracer -v '0.12.1'` succeeds before bundling

gem install therubyracer -v '0.12.1' 失败,似乎与编译有关的错误

在此之前,libv8 gem存在问题,但现在由于以下SO帖子而安装.

由于El Capitan的变化,为小牛队修复红宝石的指南似乎不起作用？

ln: /usr/bin/cpp: Operation not permitted 

Answer 1

1. 通过app store安装xcode
2. 为xcode(xcode-select --install)安装'命令行工具'
3. 如果使用rbenv,安装红宝石后需要 rbenv rehash

4. 假设您已经运行gem install bundler并遇到错误,请删除您的混乱:

   gem uninstall libv8
   gem uninstall therubyracer
   brew rm v8
   

5. 安装gcc4.2

   brew tap homebrew/dupes
   brew install apple-gcc42
   

6. 安装v8

   brew tap homebrew/versions
   brew install v8-315
   brew link --force v8-315
   

7. 安装宝石

   gem install libv8 -- --with-system-v8
   gem install therubyracer
   

   如果你得到dyld: lazy symbol binding failed: Symbol not found,@ abbaltazar建议一个替代方案:

   bundle config --local build.libv8 --with-cxx=/usr/local/bin/g++-4.2
   bundle install
   

Answer 2

@ xxjjnn的回答我仍有问题.github的以下答案解决了这个问题.我目前的设置:El Capitan 10.11.4和Xcode 7.3.

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

Answer 3

Github页面上提供的答案therubyracer对我有用:

brew tap homebrew/versions
brew install v8-315
brew link --force v8-315
gem install libv8 -- --with-system-v8
gem install therubyracer

Answer 4

我将 gem therubyracer 更新为 0.12.2，然后在 rails 存储库中运行以下命令：

$ brew install v8-315
$ bundle config --local build.libv8 --with-system-v8
You are replacing the current local value of build.libv8, which is currently nil
$ bundle config --local build.therubyracer --with-v8-dir=$(brew --prefix v8-315)
You are replacing the current local value of build.therubyracer, which is currently nil

最后

bundle install
