在OS X 10.8.2上構建ember.js失敗

Question

在Mac OS X系統（10.8.2）上，安裝了以下工具：

• Ruby，1.9.3p362（2012-12-25修訂版38607）[x86_64-darwin12.2.0]，通過brew
• Bundler，1.2.3通過gem install bundler
• rake，10.0.3通過gem install rake

無法從源代碼構建Ember。 下面是運行rake dist時的錯誤日志：

± ~/dev/ember.js (master ✓) ⚡ rake dist
/usr/local/Cellar/ruby/1.9.3-p362/lib/ruby/gems/1.9.1/gems/rake-10.0.3/lib/rake/rake_module.rb:25: warning: redundant nested repeat operator

通過查看#emberjs中的Ember Data構建說明和討論，您似乎需要首先運行bundle 。 這樣做可以成功安裝少量捆綁軟件，盡管它會在最后提示您輸入管理員密碼“將捆綁的RubyGems安裝到您的系統”。

如果然后運行此命令以查看安裝了哪些gem，則可以看到一個gem特別拒絕安裝。 按照建議運行bundle install不能解決此問題。

± ~/dev/ember.js (master ✓) ⚡ bundle exec rake -T
https://github.com/pangratz/github_downloads.git (at master) is not checked out. Please run `bundle install`

Twitter的建議是運行bundle rake dist 。 這將產生：

± ~/dev/ember.js (master ✓) ⚡ bundle rake dist
Could not find task "rake".

另一個用於bundle exec rake dist ：

± ~/dev/ember.js (master ✓) ⚡ bundle exec rake dist
https://github.com/pangratz/github_downloads.git (at master) is not checked out. Please run `bundle install`

此時運行bundle install將安裝gem列表，但最后要求輸入管理員密碼並報告成功。 #emberjs的一個想法是，這意味着它正在將gems安裝到我的系統中，而不是沙盒環境中， 這是這里的真正問題。

可以采取什么措施來克服這種捆綁/耙錯誤？

Answer 1

這是一個對我有用的解決方案：

cd <your ember clone>
curl -L https://get.rvm.io | bash -s stable --ruby
rvm install 1.9.3
rvm use 1.9.3
rvm rubygems latest
bundle install
rake dist
