javascript - 在 OS X 10.8.2 上构建 ember.js 失败

Question

在 Mac OS X 系统 (10.8.2) 上，安装了这些工具:

• Ruby，1.9.3p362(2012年12月25日修订版38607)[x86_64-darwin12.2.0]，通过brew
• Bundler，1.2.3，通过 gem 安装 bundle 程序
• rake，10.0.3，通过gem install rake

不可能从源代码构建 Ember。以下是运行rake dist时的错误日志:

通过查看 #emberjs 中的 Ember Data 构建说明和讨论，您似乎需要首先运行 bundle。这样做会成功安装一些 bundle ，但最后会提示输入管理员密码“将 bundle 的 RubyGems 安装到您的系统中”。

如果您随后运行此命令来查看安装了哪些 gem，您会发现有一个 gem 特别拒绝安装。按照建议运行 bundle install 并不能解决此问题。

± ~/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 的建议是运行 bundle rake dist。这会产生:

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

另一个用于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`

此时运行bundle install会安装gem列表，但最后要求输入管理员密码并报告成功。 #emberjs 的一个想法是，这意味着它将 gems 安装到我的系统中，而不是沙盒环境中，这才是真正的问题。

可以采取什么措施来克服这个 bundle/rake 错误？

Answer 1

这是一个对我有用的解决方案:

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
