gem uninstall libv8
brew install v8
gem install therubyracer
gem install libv8 -v '3.16.14.3' -- --with-system-v8

这是10.10它对我有用的唯一方法(ruby 2.1.2)

或者尝试gem install libv8 -v 'XX.XX.XX' -- --with-system-v8添加gem的版本:)

然后只是捆绑你的项目宝石

bundle install

看到红宝石Github问题。

希望它可以帮助别人。

也许它会对某人有用但我在安装therubyracer时遇到问题(因为libv8存在问题)解决方案是卸载我安装的所有libv8。安装therubyracer

看起来这已经在上游修复了。对我和@aurels以及@Mike Causer和@Juanda有用的是：

1
bundle update libv8

这对我的Yosemite和Ruby 2.1.5(Ruby通过RVM)非常有用。

1
gem install libv8 -v '3.16.14.3' -- --with-system-v8

之前它给了我libv8 gem版本3.16.14.3的错误Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

我能够在rm Gemfile.lock之后继续使用红宝石赛车

预先：
我通过brew install v8安装了v8，然后执行了gem install libv8 -v '3.16.14.3' -- --with-system-v8

我正在跑10.10优胜美地

只有这在我的Yosemite，Ruby 2.1.2中适合我：

1

3
gem install libv8 -v '3.16.14.3' -- --with-system-v8
brew link --overwrite v8-315 --force
gem install therubyracer -v '0.12.2' -- --with-system-v8

他们已在最新版本的libv8中更正了此问题。请参阅：https：//github.com/cowboyd/libv8/issues/123

你应该从github repo安装，在rails中我添加了一行到我的gemfile，就像这个gem"libv8", git:"git://github.com/cowboyd/libv8.git", submodules: true

编辑：

这显然只能解决一些问题。我安装了新版本的libv8，但现在rubyracer还在寻找另一个我认为的？还在调查它。

相关讨论

我在优胜美地遇到了同样的问题。我的解决方案与上面的解决方案类似。

使用gem uninstall libv8删除可能安装的任何内容。

在您的Gemfile中保留therubyracer，但删除对libv8的任何显式引用。

运行bundle install。

然后libv8作为依赖项安装得很好。

更新了2018年的答案。

我在High Sierra，Homebrew 1.6.1

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@3.15/

这对我有用吗

由于他原来的答案，信用去了@coding-addicted。

经过几个小时的尝试，只需升级ruby工作：

1
brew install ruby

然后将以下内容添加到gem文件中：

1
2
gem 'libv8'  
gem 'therubyracer'

这是因为与libv8的一些冲突，尽管你可以只为rubyracer分配一个版本，它将被安装：

更改gemfile中的以下内容：

gem'therubyracer'，'?> 0.12.1'

并进行捆绑安装

这个解决方案对我有效，遵循Jakub Troszok的解决方案，只需稍作改动

根据以下评论，对我有用的是什么

https://github.com/cowboyd/therubyracer/issues/304#issuecomment-62046085

是删除Gemfile.lock然后运行bundle install

一个可能遇到我的问题的人：我最终在RVM中卸载我的ruby版本，然后重新安装它。这似乎使用最新版本的xcode工具中的正确依赖来编译ruby。

1
2
3
rvm list
rvm uninstall ruby-x.x.x
rvm install ruby-x.x.x

我做了以下

1
gem install therubyracer

现在安装therubyracer 0.12.1，安装依赖libv8 (3.16.14.7 x86_64-darwin-14)安装没有错误。

我使用ruby 2.1.5执行此操作，我通过以下方式安装：

1
CC=/usr/bin/gcc rbenv install 2.1.5

我在运行brew upgrade ruby-builds后做了什么。

安装ruby 2.1.5后，我也跑了

1
gem upgrade --system

获得rubygems-update 2.4.5
