libv8(3.11.8.17)在Mac上捆绑安装错误

Question

我将ruby升级到1.9.3,现在我无法启动服务器.当我运行bundle install时,它说

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.

当我试图安装那个宝石时,它说

ERROR:  Error installing libv8:
        ERROR: Failed to build gem native extension.

        /Users/Erica/.rvm/rubies/ruby-1.9.3-p194/bin/ruby extconf.rb

我是一个HTML/CSS编码器,不是真正的Ruby开发人员,所以任何想法都非常感激.

Answer 1

我使用以下命令解决了这个问题:

gem install libv8 -v 3.11.8.17 -- --with-system-v8

它适用于Mavericks上的RVM.

Answer 2

尝试在自制程序中重新安装v8:

gem uninstall libv8
brew install v8
gem install libv8

Answer 3

我已经遇到过这个问题几次了，我首先尝试的是（重新）安装command line tools。正常情况下应该可以工作。

另一种成功的尝试是卸载libv8，然后再次安装。这需要很长时间...
