ruby-on-rails - 在 mac 上运行 "bundle install"时出错 - therubyracer 安装失败

Question

我第一次尝试在运行 OS X 10.9 (Mavericks) 的新 macbook pro 上安装 rails，但我在安装 therubyracer 时遇到了问题。当我执行“捆绑安装”时，出现此错误:

An error occurred while installing therubyracer (0.10.2), and Bundler cannot continue. Make sure that gem install therubyracer -v '0.10.2' succeeds before bundling.

然后我按照他们的指示运行
gem install therubyracer -v '0.10.2'
然后我收到此错误消息:

Building native extensions. This could take a while... ERROR: Error installing therubyracer: ERROR: Failed to build gem native extension.

Gem files will remain installed in /Library/Ruby/Gems/2.0.0/gems/therubyracer-0.10.2 for inspection. Results logged to /Library/Ruby/Gems/2.0.0/gems/therubyracer-0.10.2/ext/v8/gem_make.out

我不确定这是什么意思或如何解决这个问题。

我真正想做的就是运行我的 Rails 项目。

有谁知道是什么问题？

Answer 1

做这个:

$ gem uninstall libv8 # ignore if this fails
$ gem install libv8 -v 3.16.14.3 -- --with-system-v8 # 2013-08 x86_64-darwin-12 (32.6 MB)

同时编辑您的 Gemfile并强制更新版本的 therubyracer

gem "therubyracer", "~> 0.12"

然后再试一次:

$ bundle update
