Question

我无法在Yosemite 10.10上安装therubyracer gem。

这是日志：

Answer 1

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

这是它在10.10（ruby 2.1.2）上为我工作的唯一方式

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

Answer 2

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

然后只是捆绑你的项目宝石

这是它在10.10（ruby 2.1.2）上为我工作的唯一方式

Answer 3

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

看到红宝石Github问题。

希望它可以帮助别人。

Answer 4

也许这对某人有用，但我在安装therubyracer时遇到问题（由于libv8存在问题）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%)
Fetching: libv8-3.16.14.7-x86_64-darwin-14.gem (100%)
Successfully installed libv8-3.16.14.7-x86_64-darwin-14
Building native extensions.  This could take a while...
Successfully installed therubyracer-0.12.0
2 gems installed

我希望这有助于某人。

Answer 5

似乎这已在上游修复。对我和@aurels以及@Mike Causer和@Juanda有用的是：

bundle update libv8

Answer 6

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

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

之前它给了我libv8 gem version 3.16.14.3

的错误Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

Answer 7

我可以在rm Gemfile.lock

之后继续使用红宝石赛车

事先：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

我正在运行10.10 Yosemite

Answer 8

在我的Yosemite，Ruby 2.1.2中只有这个适用于我：

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

Answer 9

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

您应该从github repo安装，在rails中我添加了一行到我的gemfile，如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。

Answer 10

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。

Answer 11

更新了2018年的答案。

我在High Sierra，在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/

对我有用。

为他的original answer提供@编码 - 上瘾。

Answer 12

经过几个小时的尝试，只需升级ruby就可以了：

brew install ruby

然后将以下内容添加到gem文件中：

gem 'libv8'  
gem 'therubyracer'

Answer 13

在编码上瘾者的答案时，对我有用的是使用--with-v8-dir=/usr/local/Cellar/v8@3.15/3.15.11.18_1而不是/usr/local/opt/v8-315的本地酿造目录v8。

这在brew install命令Summary的{{1}}中可见。

Answer 14

该解决方案在遵循Jakub Troszok的上述解决方案之后，对我很有效

gem uninstall libv8
gem install therubyracer -v '0.12.1'
    Fetching: libv8-3.16.14.19-x86_64-darwin-18.gem (100%)

    2 gems installed
gem install libv8 -v '3.16.14.17' -- --with-system-v8  (if the libv8 version required for your project is different from the one installed by rubyracer)
bundle install

Answer 15

对任何可能遇到我的问题的人提出警告：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。

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

Answer 16

基于以下评论，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

Answer 17

这也是由于与libv8的一些冲突而发生的，尽管你可以只为rubyracer分配一个版本并将其安装：

更改gemfile中的以下内容：

gem'therubyracer'，'〜＆gt; 0.12.1'

并进行捆绑安装

Answer 18

我做了以下

gem install therubyracer

现在安装therubyracer 0.12.1，它会安装已安装但没有错误的依赖项libv8 (3.16.14.7 x86_64-darwin-14)。

我使用ruby 2.1.5通过以下方式完成此操作：

CC=/usr/bin/gcc rbenv install 2.1.5

我在运行brew upgrade ruby-builds之后做了。

安装ruby 2.1.5后，我也跑了

gem upgrade --system

获取rubygems-update 2.4.5

如何在10.10 Yosemite上安装therubyracer gem？
