Rake 在多台机器上中止。编译错误？
Rake aborted on multiple machines. CompilationError?
我的 Rails 应用程序遇到这个问题很长时间了。我终于有时间搞砸了，但我不明白问题出在哪里。在 Phusion Passenger 中我得到这个错误，在我的 Ubuntu 服务器上我得到这个错误，现在在 Heroku 我仍然看到这个错误。
我已经使用 heroku login 在终端中登录到 Heroku，然后我 运行 rake 命令：heroku run rake db:version --app tara-crammer-designs.
这是我看到错误的地方：

这是什么意思？我该如何解决这个问题以及 运行 我的迁移？
看起来您的一个 gem (fastimage_inline) 需要本机库 libgd，但 heroku 不提供它。 google 中的第一个 link 对于 'libgd heroku' 可能会有帮助：http://www.developwith.com/how-do-i/ruby/add-image-processing-heroku-buildpack.html
