他们在libv8的最新版本中纠正了这个问题。见：

您应该从github repo进行安装，在rails中，我在gemfile中添加了一行内容，如下

gem“libv8”，git:git://github.com/cowboyd/libv8.git，子模块：true

编辑：

这显然只解决了部分问题。我安装了新版本的libv8，但现在rubyracer仍在寻找另一个版本？还在调查

git clone https://github.com/cowboyd/libv8.git
cd libv8
bundle install
bundle exec rake clean build binary
gem install pkg/libv8-3.16.14.3-x86_64-darwin-12.gem #note that libv8 version may change, so tab through files in pkg/, also remember to use the one with version specified

然后把你的项目珍宝打包

这是我在10.10版（ruby 2.1.2）上工作的唯一方式

或者尝试

gem安装libv8-v'XX.XX.XX'--with-system-v8

添加gem的版本：）

Mac OS Catalina的更新：

brew tap homebrew/versions
brew install v8@3.15
brew link --force v8@3.15
gem install libv8 -v 'XX.XX.XX' -- --with-system-v8
gem install therubyracer

也许它对某些人有用，但我在安装RubyRacer时遇到了问题（因为libv8的问题），解决方案是卸载我安装的所有libv8。安装therubyracer

$ gem uninstall libv8
$ gem install therubyracer -v '0.12.0'
Fetching: libv8-3.16.14.7-x86_64-darwin-14.gem ( 57%)

Building native extensions.  This could take a while...

我希望这对某人有帮助

我在约塞米蒂也有同样的问题。我的解决方案与上面出现的类似

使用

gem uninstall libv8

删除可能安装的任何内容

将rubyracer保留在GEM文件中，但删除对libv8的任何显式引用

运行

捆绑安装

libv8作为一个依赖项安装得很好

在

rm Gemfile.lock

事先：我通过

brew install v8

安装了v8，然后通过

gem安装了libv8-v'3.16.14.3'--with-system-v8

我运行的是约塞米蒂10.10

这似乎已经在上游修复了。对我和@aurels、@Mike Causer和@Juanda有效的是：

bundle update libv8

我做了以下几件事

gem install therubyracer

它现在安装了Rubyracer 0.12.1，它安装了依赖项libv8（3.16.14.7 x86_64-darwin-14），安装时没有错误

我使用ruby 2.1.5实现了这一点，我通过以下方式安装了ruby 2.1.5：

CC=/usr/bin/gcc rbenv install 2.1.5

我在运行

brew升级ruby builds

后执行了此操作

在安装了ruby 2.1.5之后，我还运行了

gem upgrade --system

要在尝试简单升级ruby几个小时后获得rubygems更新2.4.5

，请执行以下操作：

brew install ruby

然后将以下内容添加到gem文件：

gem 'libv8'  
gem 'therubyracer'

这也是由于与libv8存在一些冲突而导致的，不过您可以只为rubyracer分配一个版本，然后安装它：

在文件中更改以下内容：

宝石“therubyracer”，“~>0.12.1”

根据下面的评论，安装适合我的bundle

是删除Gemfile.lock，然后运行bundle安装

这在我的Yosemite和Ruby 2.1.5（Ruby到RVM）上运行得非常好

早些时候，它给了我一个错误

Gem:：Ext:：BuildError:error:未能构建Gem本机扩展。

对于libv8 Gem版本3.16.14.3

只有在我的约塞米蒂Ruby 2.1.2中，这对我有效：

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

任何可能遇到我的问题的人都会遇到这样的问题：我最终在RVM中卸载了我的ruby版本，然后重新安装了它。这似乎使用了最新版本的xcode工具中正确的依赖项来编译ruby

rvm list
rvm uninstall ruby-x.x.x
rvm install ruby-x.x.x

这次没有一个答案对我有用。我也用过这个：

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

看见

rvm list
rvm uninstall ruby-x.x.x
rvm install ruby-x.x.x

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

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/

gem uninstall libv8
