Ruby 从主分支构建ember.js时遇到的问题

我使用的是macbook pro，安装了OSX 10.7.5，我曾多次尝试按照github页面上的步骤构建ember.js，基本上是在克隆存储库中运行“rake dist”。但它不起作用。当我运行“rake dist”时，请在下面找到我的控制台输出。由于我不是ruby专家，我想知道是否有人能为我指明方向，因为我不理解阻止我构建ember.js的错误

您是否安装了nodejs？
从文档

如果您是在Linux下构建的，您将需要一个JavaScript运行时来进行精简。您可以安装nodejs或gem安装rubyracer

假设Mac也一样，我让它工作了：

export RUBYOPT='-E utf-8'

成功了。

我将结束这个问题。

是的，安装了nodejs。我试着在Ubuntu机器上构建，但它能正常工作，所以我放弃了在Mac上构建ember.js的想法：（我也试着安装therubyracer（虽然在Mac上）谢谢你。Alex你试过bundle exec rake dist吗？刚试过，还是一样的错误。。。

export RUBYOPT='-E utf-8'
