无法在Heroku上部署twitter-bootstrap-rails gem，因为therubyracer编译失败

Question

我的Gemfile中有以下gem：

gem 'twitter-bootstrap-rails', :github => 'seyhunak/twitter-bootstrap-rails'

这是这个项目的名称：https://github.com/seyhunak/twitter-bootstrap-rails

其中一个依赖项是therubyracer ( https://github.com/seyhunak/twitter-bootstrap-rails/blob/master/twitter-bootstrap-rails.gemspec#L27 )：

s.add_dependency          'therubyracer', '>= 0.11.0beta5'

但是，当我尝试将其推送到Heroku时，我得到了以下错误：

Installing therubyracer (0.11.0beta8) with native extensions
       Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

还有没有人遇到过这种情况？

我猜Heroku和therubyracer有问题，但是我有什么办法解决这个问题吗？

Answer 1

This commit是刚刚制作的，它从宝石规范中删除了therubyracer，我猜这应该可以解决你的问题。只需运行bundle update twitter-bootstrap-rails获取它，然后再次推送到heroku。
