我无法在Yosemite 10.10上安装therubyracer gem。

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:)

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

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%)

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

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.
答案 6 :(得分:6)
我可以在rm Gemfile.lock
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

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

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。
答案 9 :(得分:3)
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
。

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。

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'
答案 12 :(得分:0)
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。

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。

是删除Gemfile.lock然后运行bundle install
答案 16 :(得分:0)
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','〜> 0.12.1'
并进行捆绑安装
答案 17 :(得分:0)
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
