我正在尝试安装libv8 3.16.14.3,但使用最新的稳定rvm和ruby-1.9.3-p125在OSX Mavericks上出错 .
这是运行命令'gem install libv8'的输出:

这是因为OS X 10.9使用的是GCC 4.8版本 . 在拉取请求(https://github.com/cowboyd/libv8/pull/95)中提到的旧版本的libv8中不正式支持此功能 . 请尝试在你的Gemfile(或)中提升libv8的版本
bundle update
就足够了 . 希望这可以帮助 .来自libv8 README
Bring your own V8
因为libv8是therubyracer使用的V8引擎的接口,所以即使已经安装了V8,也可能需要使用libv8 . 如果您希望使用自己的V8安装,而不是为您构建,请使用--with-system-v8选项 .
使用RubyGems:
使用Bundler(在您的Gemfile中):
请注意,如果您打算运行自己的V8,则必须安装V8及其标头(可在libv8-dev中找到Debian发行版) .
Bring your own compiler
您可以通过在编译之前设置CXX环境变量,或者通过在bundle配置中添加--with-cxx =选项来指定您选择的编译器:
编辑:
如果
therubyracer
引发此问题,请按照rider_on_rails here的建议尝试以下操作:您可以在Mavericks上实际安装该版本:
我可以确认这适用于rbenv和ruby 1.9.3p448
El Capitan解决方案对我来说:
REQUIRED_LIBV8_VERSION
对我来说是3.16.14.7
,但你需要检查你的捆绑中需要哪一个(这是rails4.2.5
)您可能还需要以超级用户身份运行上述命令(如果您的gem和系统库是全局的)
当我尝试接受的答案时,libv8将成功安装
gem install libv8
,但bundle install
将在libv8上失败 . 我认为bundle install
试图安装不同版本的libv8 . 我找到了一个适合我的解决方案 .我需要libv8,因为therubyracer依赖它 . 为了安装它,我注意到在
gem_make.out
日志中未能安装的版本为therubyracer . (gem_make.out
日志的路径将在失败消息中 . )在我的情况下,它是3.16.14.7 . (这个版本可能会随着时间的推移而改变,以防你从现在开始读这三年 . )然后我这样做了:gem install libv8 -v 3.16.14.7 -- --with-v8-lib
< - 注意接受答案的不同标志这允许这个工作:
gem install therubyracer
这让我完成了我的
bundle install
.这对OSX优胜美地有用 .
https://github.com/cowboyd/therubyracer/issues/339
jasonlynes在该链接上找到的解决方案为我提供了诀窍 . 其他任何东西都不起作用 .
试试我在这个问题中总结的内容:"gem install therubyracer -v '0.10.2'" on osx mavericks not installing
它对我有用(OS X Mavericks)
当我从OSX Mountain Lion升级到OSX Mavericks时,我遇到了同样的问题 . 接受的答案适用于libv8,但当我去捆绑安装therubyracer gem时却没有 .
从ruby-1.8.7-p354升级到ruby-1.8.7-375对我来说是个窍门 . 安装了libv8(3.16.14.3-x86_64-darwin-13)和therubyracer(0.12.0)宝石没有问题 .
假设你使用rbenv:
This worked fine for me:
尝试安装这个预编译的gem:
https://dl.dropboxusercontent.com/u/7919548/gems/libv8/libv8-3.11.8.17-x86_64-darwin-13.gem(sha1:5ce07aaf4085fff5a5e10fe018fd6b22021bef3b)
或者,如果您更喜欢自己 Build :

感谢Felix Bünemann的修复!
您可以尝试通过the libv8 github site.上提到的方法手动编译和安装gem .
在MAC-Yosemite中使用RVM环境和ruby-2.1.1版本
gem install libv8 -v 3.16.14.3 -- --with-v8-lib gem install therubyracer
它在上述命令的帮助下工作,可以确认这一点 .
对我来说真正有用的是将ruby升级到2.2.0,删除Gemfile.lock并再次捆绑 .
像魅力一样工作!
这对我有用 .
用您的版本替换
3.16.14.7
.我在El Cap遇到过类似的问题 . 这就是我做的 .
然后,
最后,
我尝试了之前答案中概述的一些解决方案,但发现运行bundle(安装其他的,缺少的gems)会尝试重新编译libv8(尽管已经有了使用
--with-system-v8
)成功安装它,因此遭遇同样的问题 .最后,我发现删除libv8 gem,从rubygems获取gem文件,然后手动安装带有
--with-system-v8
标志的.gem
文件 .即
感谢Gaurav Agarwal's answer带领我走正确的道路!
我在另一个项目中使用了Xcode的测试版并且忘记了 . 切换回
xcode-select
. 就像是:从Gemfile中删除:
gem'therubyracer',: platforms =>:ruby
