无法安装libv8 3.11.8.17 gem。我已经环顾四周,发现它不支持Windows。尽管我还在寻找变通办法?

An error occurred while installing libv8 (3.11.8.17), and Bundler cannot
continue.
Make sure that `gem install libv8 -v '3.11.8.17'` succeeds before bundling.
我不想使用therubyracer,老实说,我不知道gem依赖于libv8。安装Python27和设置PATH没有任何作用。除了更换平台,我还能做什么?或者,v8.dll可能有一个变通方法,可从https://github.com/hiranpeiris/therubyracer_for_windows我似乎不明白?
试试这个
gem install libv8 -v '3.16.14.3' -- --with-system-v8
从这里回答
安装libv8时出错:错误:无法构建gem本机扩展
我在prod上只在Linux环境中使用libV8和TheRubyRacer。我在Gemfile:中分离它们
group :production do
gem 'libv8', '~> 3.11.8.3'
gem 'therubyracer', :platform => :ruby
end
然后我捆绑安装而不生产:
bundle install --without production
(请参阅SO文章:为什么';bundle';在我的开发机器上安装生产宝石?)
这似乎避免了整个V8在Windows上的争论。
