在OS X 10.9+上安装libv8 gem

我试图安装libv8 3.16.14.3，但在OSX Mavericks上使用最新的稳定rvm和ruby-1.9.3-p125上出现错误。

这是运行命令'gem install libv8'的输出:

当前回答

当我尝试接受的答案，libv8将成功安装与gem安装libv8，但捆绑安装将失败在libv8。我认为那个包安装试图安装一个不同版本的libv8。我找到了一个适合我的解决方案。

我需要libv8，因为therubyracer依赖于它。为了安装它，我在gem_make中注意到安装失败的版本。therubyracer的日志。gem_make. xml文件的路径。退出日志将出现在失败消息中。)对我来说是3.16.14.7。(这个版本可能会随着时间的推移而改变，以防你三年后再读这篇文章。)然后我这样做了:

Gem安装libv8 -v 3.16.14.7 -- --with-v8-lib <——注意不同的标志从接受的答案

这使得这个方法可行:

Gem安装therubyracer

这让我完成了我的包安装。

在OSX优胜美地，这招很管用。

其他回答

从Gemfile删除:

Gem 'therubyracer'，:platforms =>:ruby

2014-08-12 02:12:46

这对我来说很有效:

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)

或者如果你更喜欢自己建造:

  git clone https://github.com/cowboyd/libv8.git
  cd libv8
  git checkout 3.11
  bundle install
  bundle exec rake clean build binary
  gem install pkg/libv8-3.11.8.17-x86_64-darwin-13.gem

感谢Felix Bünemann的修复!

这些对我都没有帮助……无论我做什么，我的宝石安装therubyracer一直抱怨这个错误:

Unable to find a compiler officially supported by v8.

最终帮助我的是我在https://www.bountysource.com/issues/82833405-libv8-fails-to-build-on-catalina-10-15上偶然发现的另一个论坛

最后的解决方案对我来说是有效的:

我必须将这些行添加到我的.zshrc文件中:

export CXX=clang++
export GYPFLAGS=-Dmac_deployment_target=10.15

然后我必须运行这些命令:

source ~/.zshrc
brew tap homebrew/homebrew-core
brew install v8@3.15
gem uninstall therubyracer
gem uninstall libv8
gem install libv8 -v '3.16.14.19' -- --with-system-v8
gem install therubyracer -v '0.12.3' -- --with-v8-dir=/usr/local/opt/v8@3.15
bundle install

我希望其他人觉得这有用!

尝试我在这个问题中总结的内容:“gem install therubyracer -v '0.10.2'”在osx mavericks上未安装

对我来说很管用(OS X Mavericks)

我尝试了之前的答案中列出的一些解决方案，但发现运行bundle(安装其他，丢失的gems)会试图重新编译libv8(尽管已经使用——with-system-v8成功安装了它)，因此遇到了同样的问题。

最终，我发现删除libv8 gem，从rubygems中获取gem文件，然后手动安装带有——with-system-v8标志的.gem文件对我来说很有效。

i.e.

gem uninstall libv8
gem fetch libv8 -v LIBV8_VERSION
gem install libv8-LIBV_VERSION.gem -- --with-system-v8
bundle

多亏了高拉夫·阿加瓦尔给我的答案是你指引我走上了正确的道路!
